Rationales
Included
, Velocity The rate of change of displacement
acceleration The rate of change of velocity
Work done A measure of the energy transferred during a process
Law of Conservation of Energy Energy can neither be created or destroyed, just changes from one form to another.
Momentum The product of an objects mass times its velocity
Law of Conservation of Momentum In the absence of external forces the total momentum before a collision is equal to
the total momentum after a collision
Elastic collision An elastic collision is one in which kinetic energy is conserved.
Inelastic collision An inelastic collision is one in which kinetic energy is lost
Newton's first Law An object will remain at rest or continue at constant speed in a straight line unless
acted on by an unbalanced force
Newton's Second Law The acceleration of an object is proportional to the unbalanced force acting on it
and inversely proportional to its mass. (a = F/m)
Newton's Third Law If a body A exerts a force on body B then body B exerts an equal and opposite force
on body A.
Newton One Newton is the force required to give an object of mass 1kg an acceleration of
1ms-2.
