Question Answer
newtons first law of motionan object remains at rest or in uniform motion unless acted on by a force
newton's second lawacceleration is proportional to resultant force acting
newtons 3rd law of motion2 objects interacting have equal and opposite forces on each other
what is the principle of conservation of momentumfor a system of interacting objects, total momentum remains constant provided no external force acts on the system
what is an elastic collisionwhen two objects interact without loss of kinetic energy
perfectly inelastic?when the colliding objects stick together
partially inelasticwhen the colliding objects move apart and have less kinetic energy after the collision than before
