Newton's 3 Laws
| Term | Definition |
|---|---|
| Newton's 1st Law | An object in motion/ rest will stay in motion/ rest unless an outside force is acting on that object. |
| Newton's 2nd Law | The force acting on an object is equal to the mass of that object times its acceleration. F = MA |
| Newton's 3rd Law | For every action force, there is an equal and opposite reaction. |
| Speed | The distance traveled by an object divided by the time taken to travel that distance. |
| Velocity- | The speed of an object in a particular direction. |
| Acceleration | The rate at which velocity changes. |
| Force | A push or pull acting on an object. |
| Net Force | The combination of all the forces acting on an object. |
| Balanced Net Force | When the forces acting on an object produce a net force of 0 newtons. |
| Unbalanced Net Force- | When the forces acting on an object produce a net force other than 0 newtons. |
| Friction | The force that opposes motion between two surfaces that are in contact. |
| Gravity | The force of attraction between two objects with mass. |
| Inertia | The natural tendency of objects to resist changes in their state of motion. |
| Momentum | The mass of an object times the velocity of an object; or “Mass in motion”. |
| Elastic Collision- | A collision in which objects bounce off each other. |
| Inelastic Collision | A type of collision in which objects stick together. |
| Conservation of Momentum | The total momentum of all objects before a collision equals the total momentum of all objects after a collision. |
