| explanation | few words |
| energy associated with the state of separation between two objects that attract each other by the gravitational force | |
| mass x velocity=mv | |
| the rate at which the velocity of an object changes | |
| body that rotate without change in its shape | |
| frictional force that opposes the motion | |
| the motion of a body when air resistance is negligible and the motion can be considered due to the force of gravity alone | |
| tell one of requirements for equilibrium | |
| an axis that does not move where rotation occurs | |
| a type of collision in which the kinetic energy before and after the collision remains the same | |
| define uniform circular motion | |
