| Newton's second law of motion | net force causes acceleration in the direction of the force |
| air resistance | force air exerts on a moving object |
| terminal velocity | highest velocity that will be reached by a falling object |
| projectile | anything thrown or shot through the air |
| centripetal acceleration | acceleration toward the center of a curved or circular path |
| centripetal force | force acting toward the center of a curved or circular path |
| artificial satellite | manmade devices that orbit Earth |
| Newton's third law of motion | When one object exerts a force on a 2nd, it exerts a force that is equal and opposite |
| momentum | property of a moving object because of its mass and velocity |
| law of conservation of momentum | total momentum of a group of objects does not change |
| formula for 2nd law | F = m x a |
| formula for momentum | p = m x v |
