Order by
10 terms
Terms | Definitions |
|---|---|
 Newton's second law of motion | a net force acting upon an object causes the object to accelerate 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 |
| centripital acceleration | acceleration towards the center of a curved or circular path |
| centripital force | force acting towards the center of a curved path |
| artificial satellite | human-made devices that orbit Earth |
| Newton's third law of motion | action-reaction: when one object exerts a force on a second object, the second one exerts a force on the first that is equal in size and opposite in direction |
| momentum | property of a moving object based on its mass and velocity |
| law of conservation of momentum | states that the total amount of momentum of a group of objects does not change unless outside forces act on the objects |
