Document Summary
Magnitude amount or size of force applied (arrow drawn to scale) Direction path along which force is applied (arrow indicates direction) Point of application point of force application on body or system receiving it. Line of action straight line through point of application extending indefinitely along direction of force: also known as line of pull (muscles) or line of force, allows us to determine the movement arm distance. Body translating (moving in its entirely) in a straight line or along a curved path. Change in distance or position with respect to a reference point. Slide" joint glides in the body: angular motion (rotation or spin) Movement in a plan about an axis perpendicular to the plane (perfect circle, stays the same distance from the attachment point) Results when force is applied to an object which is fixed or attached. Swing" typical joint actions in the body.
