Movement in a curved / straight line where all body parts move the same distance at the same time in the same direction
1 of 7
Law of inertia
The resistance an object has to a change in its state of motion i.e. the heavier the mass of an object, the larger its inertia
2 of 7
Law of acceleration
The acceleration of an object is directly proportion to the force exerted on it: F = ma
3 of 7
Law of action and reaction
For every action [force] there is an equal and opposite reaction e.g. sprinter pushes back on blocks [action] and blocks push forward on athlete [reaction]
4 of 7
Ground Reaction Foce
Force emitted on the ground by the body
5 of 7
Scalar Quantity
Measurements described in terms of size e.g. speed, distance, mass and temp
6 of 7
Centre of mass
Point of balance in the body - to increase stability 1) Keep a low centre of mass 2) line of gravity should be central to the base of support 3) larger the area covered, greater the stability 3) greater the mass greater the stability (inertia)
