NettetLower limb biomechanics refers to a complex interplay between the joints, muscles, and nervous system which results in a certain patterning of movement, often referred to as ‘alignment’. Much of the debate centres around what is considered ‘normal’ and what is considered ‘abnormal’ in biomechanical terms, as well as the extent to which we … NettetWe define angular velocity ω as the rate of change of angular displacement. In symbols, this is. ω = Δθ Δt, ω = Δ θ Δ t, where an angular rotation Δθ takes place in a time Δt. The greater the rotation angle in a given amount of time, the greater the angular velocity. The units for angular velocity are degrees per second (º/s ...
