The two main components for walking and most mobile activities are the hips and the knees. The hip joint is a ball and socket joint‚ which means it can move in all directions. The knee joint is a compound condylar synovial joint and allows for flexion and extension of the leg. In this experiment the angle‚ angular velocity‚ and the angular acceleration of the knee and hip were analyzed in oscillatory motion. In the first set of experiments‚ the independent oscillation of the hip and knee were isolated
