Newton's Third Law
For every action, there is an equal and opposite reaction. Golfers push into the ground to make the ground push back, generating speed.
The 3 Forces
- Horizontal/Linear: Pushing side-to-side (sway/shift).
- Torque/Rotational: Twisting the feet to rotate the pelvis.
- Vertical: Pushing straight down (the jump). Vertical force correlates most highly with driver clubhead speed.
