| inertia | (physics) the tendency of a body to maintain is state of rest or uniform motion unless acted upon by an external force |
| air resitance | upward force of air against a moving object |
| vertical | velocity in an up or down direction |
| direction | two objects with the same velocity must be moving in the same ______ |
| gravity | a force of attraction between objects that is due to their masses |
| Newton's First Law of Motion | An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted by an unbalanced force. |
| Newton's Second Law of Motion | The acceleration of an object depends on the mass of the object and the amount of force applied. |
| Newton's Third Law of Motion | Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. |
| equation for acceleration | acceleration= force/ mass a= F/m F= m x a |
