The action of the foot making contact with the ground when walking, running or jumping
A force generated when absorbing body motion landing
An impulse that moves the body
The rate of movement of rotation
The rate of change of velocity during angular movement
The amount of motion that the body has during rotation:- angular velocity x moment of inertia
The resistance of a body to a change of state when rotating
A word used to describe the motion of a mass when it is rotating or spinning
The turning effect produced by a force, measured in Newtonmetres (Nm); also known as torque
The perpendicular distance from the point of application of a force to the axis of rotation
The mass and the lever system from the mass to the fulcrum
The part of the lower system from where the effort is applied to the fulcrum
At right angles to.
For a body to be in equilibrium (balance), the sum of the clockwise moments is equal to the sum of the anticlockwise moments about the fulcrum (pivot)
The movement of a body or mass around an axis—spinning, rotating, turning
The principle that the angular momentum of an object remains constant as long as no external force (moment of torque) acts on that object
57.3 degrees
The angle at which an object is released; measured from the horizontal
The flight path of a projectile in the absence of air resistance
The horizontal motion of an object in a parabolic flight curve
The upward motion of an object in a parabolic flight curve
The highest point above the ground that an object is released
The velocity of the object when it is released from the hand
