- Kinematics describe the movements of a golf swing (speed, velocity, acceleration, rotation, etc)
- Kinetics are the forces that created the movement (forces, torques)
Traditional software packages are great at measuring kinematics (movement) but they don’t show the kinetics, or forces at play. For example, I could already see kinematically the motion of the club twisting on the downswing as the player squared the face. I could see that it twisted, and how fast it was twisting, but I wanted to know how much force/torque it took the player to twist it, and when in the swing that twisting effort started to happen. The ability to do that wasn’t out there, so I decided to solve the problem myself. I built my own software—Jacobs 3D.
