Key Definitions for Application of Forces
Footfall - The action of the foot making contact with the ground when walking, running or jumping.
Negative impulse - A force generated when absorbing body motion - landing.
Positive impulse - An impulse that moves the body.
Angular velocity - The rate of movement in rotation.
Angular acceleration - The rate of change of velocity during anglar movement.
Angular momentum - the amount of motion that the body has during rotation - Anglar Velocity x Moment of Inertia
Moment of inertia - The resistance of a body to a change of state when rotating.
Angular - A word used to describe the motion of a mass when it is rotating or spinning.
Moment - The turning effect produce by a force, measured in Newtonmetres (Nm); also known a torque.
Moment arm - The perpendicular distance from the point of…
