What is the difference between kinematics and kinetics in biomechanics?

In biomechanics, the difference hinges on what each field studies: kinematics describes motion itself, focusing on position, velocity, and acceleration without regard to what causes the movement; kinetics examines the forces and moments that produce or accompany that motion. For example, when analyzing walking, kinematics would track how the ankle angle changes over time, the speed of the leg, and the path of motion. Kinetics would look at the joint torques, muscle forces, and external forces like ground reaction forces that generate and influence that motion. So the correct description is that kinematics deals with motion parameters, while kinetics deals with the forces causing motion. The other options mix up motion and forces or bring in time or energy concepts that aren’t the defining focus here.
