Biomechanics is the study of forces and their effects on living organisms, especially in relation to human movement and sports activities. It examines how Newton's laws of motion apply to human movement and the roles of factors like friction. The chapter discusses key biomechanics concepts like types of movements, Newton's laws, and friction. It provides examples of these scientific principles in action during sports like the effect of friction on a swinging cricket ball.
