00:00:00.000 --> 00:00:02.669
hi in this call smart insight I'm going

00:00:02.669 --> 00:00:04.560
to help you understand the forces as

00:00:04.560 --> 00:00:06.660
they apply in the golf swing I know that

00:00:06.660 --> 00:00:08.040
there's a lot of confusion out there

00:00:08.040 --> 00:00:11.910
about what the forces are how you can

00:00:11.910 --> 00:00:14.250
see them or if you can see them and the

00:00:14.250 --> 00:00:16.109
general patterns so in this video I'm

00:00:16.109 --> 00:00:18.150
going to hopefully clarify some of those

00:00:18.150 --> 00:00:20.699
forces especially as they relate to the

00:00:20.699 --> 00:00:23.070
in-plane movement sometimes referred to

00:00:23.070 --> 00:00:25.980
as alpha alright before we look at how

00:00:25.980 --> 00:00:28.050
it relates to the golf swing I've got

00:00:28.050 --> 00:00:29.730
this simple little drawing to help you

00:00:29.730 --> 00:00:32.340
understand the net force because I think

00:00:32.340 --> 00:00:35.910
it's often confused for what a golfer is

00:00:35.910 --> 00:00:38.309
trying to do versus what is actually

00:00:38.309 --> 00:00:40.530
happening so okay so in this scenario

00:00:40.530 --> 00:00:43.140
I've got a cliff right and then there's

00:00:43.140 --> 00:00:46.170
a weight hanging around a pulley being

00:00:46.170 --> 00:00:49.230
held by this gentleman here now that

00:00:49.230 --> 00:00:52.140
pulley is not a string it's a cable and

00:00:52.140 --> 00:00:53.969
that's going to be important for this

00:00:53.969 --> 00:00:57.899
third situation okay now I've got the

00:00:57.899 --> 00:00:59.730
weight on a cable attached to the guy

00:00:59.730 --> 00:01:01.230
there's a couple different things that

00:01:01.230 --> 00:01:04.170
could happen scenario one he's kind of

00:01:04.170 --> 00:01:06.990
lowering it down slowly scenario two

00:01:06.990 --> 00:01:08.939
he's backing up and he's actually

00:01:08.939 --> 00:01:11.580
pulling it upward and then scenario

00:01:11.580 --> 00:01:14.270
three because it's a cable he's actually

00:01:14.270 --> 00:01:16.950
pushing it down so he's having it fall

00:01:16.950 --> 00:01:20.909
faster than gravity okay in the first

00:01:20.909 --> 00:01:24.119
scenario actually the second scenario is

00:01:24.119 --> 00:01:25.229
probably the easiest so let's start with

00:01:25.229 --> 00:01:27.299
that so in the second scenario right

00:01:27.299 --> 00:01:30.090
here he's got the cable moving up this

00:01:30.090 --> 00:01:34.500
way he is clearly pulling on the cable

00:01:34.500 --> 00:01:37.020
back towards him like this that's where

00:01:37.020 --> 00:01:39.180
the net force would be going and it

00:01:39.180 --> 00:01:40.409
would be greater than whatever the

00:01:40.409 --> 00:01:43.979
weight is with gravity on this second

00:01:43.979 --> 00:01:46.740
example we've got the weight going down

00:01:46.740 --> 00:01:49.979
so he's slowly letting it down so his

00:01:49.979 --> 00:01:51.509
hands and everything would be moving

00:01:51.509 --> 00:01:53.869
this way but because the weight is going

00:01:53.869 --> 00:01:57.960
down slower than gravity the net force

00:01:57.960 --> 00:02:00.960
is back towards him it's going to be in

00:02:00.960 --> 00:02:03.000
the same direction as him pulling up

00:02:03.000 --> 00:02:05.700
just to a lesser degree or a lesser of

00:02:05.700 --> 00:02:08.670
magnitude it's only an example three

00:02:08.670 --> 00:02:11.550
where if he was to accelerate this down

00:02:11.550 --> 00:02:13.319
greater than just what gravity would be

00:02:13.319 --> 00:02:13.770
do

00:02:13.770 --> 00:02:16.350
that he would actually have the force

00:02:16.350 --> 00:02:19.710
and his hand Direction going out towards

00:02:19.710 --> 00:02:22.470
the pulley like so now we'll talk about

00:02:22.470 --> 00:02:25.980
where this relates the golf swing but

00:02:25.980 --> 00:02:28.980
the the common thing I hear is okay if

00:02:28.980 --> 00:02:30.960
we want the forces coming back in

00:02:30.960 --> 00:02:33.300
towards you that you need to be really

00:02:33.300 --> 00:02:35.700
pulling up on the handle well understand

00:02:35.700 --> 00:02:38.160
that if you if you create a ton of club

00:02:38.160 --> 00:02:39.780
at speed and this weight is pulling away

00:02:39.780 --> 00:02:41.100
from you or the golf club is swinging

00:02:41.100 --> 00:02:42.960
away from you you're going to have a

00:02:42.960 --> 00:02:46.200
really high force pulling in towards you

00:02:46.200 --> 00:02:48.360
even though your arms are extending and

00:02:48.360 --> 00:02:51.030
kind of letting that weight up kind of

00:02:51.030 --> 00:02:53.340
pull your arms out so that's important

00:02:53.340 --> 00:02:54.480
thing to understand that the net force

00:02:54.480 --> 00:02:58.140
is a relationship of the physics

00:02:58.140 --> 00:03:01.170
happening to you or by you not

00:03:01.170 --> 00:03:02.880
necessarily what you're trying to do and

00:03:02.880 --> 00:03:05.430
what you're feeling now let's take that

00:03:05.430 --> 00:03:07.770
rope on a string analogy and apply it to

00:03:07.770 --> 00:03:08.400
the golf swing

00:03:08.400 --> 00:03:11.610
now let's specifically look at going

00:03:11.610 --> 00:03:13.950
normal down at the bottom so pulling up

00:03:13.950 --> 00:03:15.600
on the handle and having the force going

00:03:15.600 --> 00:03:18.840
more up towards you the orange dots that

00:03:18.840 --> 00:03:22.200
I have drawn represent roughly where the

00:03:22.200 --> 00:03:24.209
center of mass would be so just behind

00:03:24.209 --> 00:03:26.100
the shaft in the direction of a club

00:03:26.100 --> 00:03:28.050
head kind of like this again this is

00:03:28.050 --> 00:03:30.300
incredibly rough but we don't have to

00:03:30.300 --> 00:03:32.430
get too specific to be able to see this

00:03:32.430 --> 00:03:35.310
general pattern if we if we take a look

00:03:35.310 --> 00:03:39.240
at these dots and if we imagine just the

00:03:39.240 --> 00:03:42.000
vertical change or just the the change

00:03:42.000 --> 00:03:44.070
towards the ground kind of like this you

00:03:44.070 --> 00:03:46.350
can see as you get down here towards the

00:03:46.350 --> 00:03:48.660
bottom the vertical change between the

00:03:48.660 --> 00:03:50.040
dots gets smaller and smaller

00:03:50.040 --> 00:03:52.740
that means that the center of mass is

00:03:52.740 --> 00:03:56.240
not accelerating down towards the ground

00:03:56.240 --> 00:03:59.850
because the if it was then the space

00:03:59.850 --> 00:04:01.380
between these dots would get bigger and

00:04:01.380 --> 00:04:04.800
bigger so since the distance between the

00:04:04.800 --> 00:04:07.920
dots is getting slightly smaller that

00:04:07.920 --> 00:04:10.680
means that the force would be working up

00:04:10.680 --> 00:04:14.010
away from the ground so when we get down

00:04:14.010 --> 00:04:16.350
here where the swing where the club has

00:04:16.350 --> 00:04:18.959
a flattish path it was moving very

00:04:18.959 --> 00:04:21.299
vertically through here and then it has

00:04:21.299 --> 00:04:23.880
a flattish path that means somewhere

00:04:23.880 --> 00:04:27.650
around here which ends up being roughly

00:04:27.650 --> 00:04:29.960
when those hands are in front of the

00:04:29.960 --> 00:04:34.130
thigh it starts to flatten out and

00:04:34.130 --> 00:04:36.380
therefore the force would be working

00:04:36.380 --> 00:04:40.520
away from the ground from let's say the

00:04:40.520 --> 00:04:42.860
frame just before this all the way down

00:04:42.860 --> 00:04:46.669
through and past the impact so you can

00:04:46.669 --> 00:04:49.520
see that unless you had of an angle of

00:04:49.520 --> 00:04:51.729
attack somewhere around 90 degrees

00:04:51.729 --> 00:04:54.710
you're probably going to have the net

00:04:54.710 --> 00:04:57.650
force working away from the ground or

00:04:57.650 --> 00:05:00.889
towards you what really matters is how

00:05:00.889 --> 00:05:02.780
you apply that force away from the

00:05:02.780 --> 00:05:05.360
ground whether you do it more from your

00:05:05.360 --> 00:05:07.910
body whether you do it more by pulling

00:05:07.910 --> 00:05:10.699
and bending your arms but as you've seen

00:05:10.699 --> 00:05:13.220
you don't necessarily have to feel like

00:05:13.220 --> 00:05:15.620
you pull your hands in closer to your

00:05:15.620 --> 00:05:18.169
body in order to get the proper net

00:05:18.169 --> 00:05:20.600
force pattern the other instruction that

00:05:20.600 --> 00:05:22.220
I commonly hear is down at the bottom

00:05:22.220 --> 00:05:24.320
you want to be pulling not only up but

00:05:24.320 --> 00:05:26.990
you want to be pulling in so this is a

00:05:26.990 --> 00:05:28.850
little bit trickier to see the easiest

00:05:28.850 --> 00:05:30.139
way to see this is actually from an

00:05:30.139 --> 00:05:33.530
overhead cam but think of it in the same

00:05:33.530 --> 00:05:36.470
light as what we did from the face on we

00:05:36.470 --> 00:05:39.139
can see that at this phase in the

00:05:39.139 --> 00:05:41.960
downswing the center of mass is having

00:05:41.960 --> 00:05:43.940
some clear movement out towards the golf

00:05:43.940 --> 00:05:47.090
ball now remember if it slows down its

00:05:47.090 --> 00:05:49.580
movement out towards the golf ball or it

00:05:49.580 --> 00:05:51.139
changes direction then the center of

00:05:51.139 --> 00:05:52.849
mass starts moving away from the golf

00:05:52.849 --> 00:05:54.889
ball that means that there was a net

00:05:54.889 --> 00:05:58.310
force away from the golf ball so down

00:05:58.310 --> 00:06:00.160
here at the bottom where you can see

00:06:00.160 --> 00:06:03.620
that the the path of the club starts

00:06:03.620 --> 00:06:05.510
working back up and in that means that

00:06:05.510 --> 00:06:08.389
well before then there was a net force

00:06:08.389 --> 00:06:11.389
that is working away from the golf ball

00:06:11.389 --> 00:06:13.699
so you can see that in order to make a

00:06:13.699 --> 00:06:15.560
swing where you didn't have the net

00:06:15.560 --> 00:06:20.180
forces working back up and in or away

00:06:20.180 --> 00:06:21.650
from the ground and away from the golf

00:06:21.650 --> 00:06:23.930
ball it would be very challenging in

00:06:23.930 --> 00:06:26.389
fact it would not look very much like a

00:06:26.389 --> 00:06:28.699
golf swing at all the most important

00:06:28.699 --> 00:06:31.760
part is how you create these forces not

00:06:31.760 --> 00:06:34.419
necessarily what the forces actually are

00:06:34.419 --> 00:06:36.650
there's still a lot of stuff that we can

00:06:36.650 --> 00:06:39.020
learn from investigating these net

00:06:39.020 --> 00:06:41.180
forces but the overall pattern

00:06:41.180 --> 00:06:43.100
kind of makes sense with the general

00:06:43.100 --> 00:06:45.020
movement patterns if you're not sure

00:06:45.020 --> 00:06:46.820
what the general movement patterns are

00:06:46.820 --> 00:06:48.830
or therefore what the arms should be

00:06:48.830 --> 00:06:51.139
doing in the backswing or transition or

00:06:51.139 --> 00:06:53.300

be doing during the different phases of

00:07:14.000 --> 00:07:16.250
the swing and how to recognize the

00:07:16.250 --> 00:07:18.080
feedback as to if you're actually doing

00:07:18.080 --> 00:07:21.009
it or not
