| Newton's First Law of Motion | If the forces acting on an object are balanced, then the velocity of the object doesn't change |
| Inertia | The tendency of an object to resist a change in motion |
| 3 kinds of equilibrium an object can have | Sitting still, Steady speed in a straight line, Spinning at a steady rate |
| Newton's Second Law of Motion | The acceleration of an object depends on the objects mass, the force applied, and the direction of the force |
| Newton's Second Law Formula | F = ma |
| Gravity | An attractive force between any two objects: increases as the mass of the objects increase and increase as the distance between the objects decreases |
| Basic Forces of the Universe | Gravitational, Electromagnetic, Strong Nuclear, Weak Nuclear |
| Electromagnetic Force | Electricity, magnetism, light, heat, most day to day pushes and pulls |
| Strong Nuclear Force | Holds protons and neutrons together in the nucleus of an atom |
| Weak Nuclear Force | Causes radioactivie decay |
| On Earth, the acceleration due to gravity | 9.8 m/s/s |
| Mass | The amount of matter in an object - does not change when you leave Earth |
| Weight | The gravitational force exerted on an object - changes when you leave Earth |
| Equation used to convert mass to weight | W = mg |
| Projectile | Anything that is thrown or shot through the air |
| Centripetal Force | The net force exerted toward the center of a curved path |
| Centripetal Acceleration | Acceleration toward the center of a curved or circular path |
| Newton's Third Law of Motion | Every action has an equal and opposite reaction |
| Momentum | A measure of how hard it is to change the motion of a moving object |
| Momentum depends on | Mass and Velocity |
| Equation for momentum | p = mv |
| The Law of Conservation of Momentum | When objects run into each other or push off of each other, the total momentum of all the objects involved has to stay the same |
