an object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an unbalanced force
force=Mass*Acceleration. The rate of change of momentum of an object is proportional to the unbalance force in the direction of force.
for every action there is an equal and opposite reaction
something that is done for a particular purpose
action or response to something that has happened or has been done
