Mutual action between objects where each object exerts an equal and opposite force on the other.
The action-reaction pair of forces that occur in an interaction
Newton's third law
Whenever one object exerts a force on another, the second object exerts an equal and opposite force on the first. Or put another way, "To every action there is always an opposed equal reaction."
inertia in motion
mass * velocity
the quantity of force * time interval
change in momentum
a physical quantity that remains unghanged during a process
law of conservation of momentum
in the absence of an external force, the momentum of a system remains unchanged. (Net momentum before a collision = net momentum after a collision.)
a collision in which colliding objects rebound without lasting damage or the release of heat
a collision in which colliding objects become tangled together and generate heat
