Centripetal acceleration | | the product of its mass and velocity |
Centripetal force | | if the net force acting on an object is zero the object remains at rest |
First law of motion | | if a group of objects exerts forces only on each other their momentum doesn't change |
Gravity | | is an attractive force between any two objects |
Inertia | | the net force exerted toward the center of a curved path |
Law of conservation of momentum | | tendency of an object to resist a change in its motion |
Second law of motion | | acceleration toward the center of a curved or circular path |
Third law of motion | | states that acceleration of an object is in the same direction as the net force on the object F=ma (force= mass x acceleration) |
weight | | when one object exerts a force on a second object the second one exerts force on the first that is equal in strength and in the opposite direction |
Momentum | | the gravitational force exerted on an object |
