In the previous chapter we learned that kinematics or descriptions of motion could be used to provide information for improving human movement. This chapter will summarize the important laws of kinetics that show how forces overcome inertia and how other forces create human motion. Studying the causes of linear motion is the branch of mechanics known as linear kinetics. Identifying the causes of motion may be the most useful kind of mechanical information for determining what potential changes could be used to improve human movement. The biomechanical principles that will be discussed in this chapter are Inertia, Force-Time and Segmental Interaction.
