| 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 on by an unbalanced force | First Law of Motion |
| the acceleration of an object depends on the mass of the object and the amount of force applied | Second 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 | Third Law of Motion |
| the tendency of all objects to resist any change in motion. | inertia |
| First law of motion | "Law of Inertia" |
| Second Law formula | a = F/m |
| mass label | m |
| force label | N |
| acceleration label | a = F/m |
| momentum label | p |
| velocity | v |
| gravity | g |
| for every action there is an equal and opposite reaction | action/reaction |
| swimmer pushing water with their hand | third law example |
| ball falling, hitting the floor and bouncing back up | second law example |
| car hitting a wall and the person flying out | first law example |
| the constant velocity of a falling objecct when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity | terminal velocity |
| occurs on an object if gravity is pulling it down and no other forces are acting on it | free fall |
| depends on the object's mass and velocity | momentum |
| states that any time objects collide, the total amount of momentum stays the same | law of conservation of momentum |
| momentum of a bouncing object | bouncing momentum |
| momentum of two objects stuck to each other | sticking momentum |
| is the curved path an object follows when it is thrown or propelled near the surface of the Earth. | projectile motion |
