Inertia
To resist any change in motion
| Question | Answer |
|---|---|
| Inertia: | To resist any change in motion. |
| Non-contact force: | A force that one object can apply to another object without touching it. |
| Gravity: | An attractive force that exists between all objects that have mass. |
| Field: | A region of space that has a physical quantity (Such as force) at every point. |
| Weight: | The gravitational force exerted on an object. |
| Newton's Third Law: | The law of action/reaction. |
| Force Pair: | The forces of two objects applied to each other. |
| Normal Force: | The force that pushes perpendicular to the object's surface. |
| Elastic Collision: | When colliding objects bounce off of each other. |
| Inelastic Collision: | If objects collide and stick together, such as one football player tackling another, that is inelastic. |
| Reference Point: | The starting point you choose to describe the location or position of an object. |
| Position: | An object's distance and direction from a reference point. |
| Motion: | The process of changing position. |
| Displacement: | The difference between the initial, or starting, position and the final position. |
| Speed: | A measure of the distance an object travels in a given amount of time. |
| Velocity: | The speed and direction of a moving object. |
| Vector: | A quantity that has both magnitude and direction. |
| Newton's 1st Law: | The law of Inertia. |
| Newton's 2nd Law: | The law of Acceleration. ( Force = Mass X Acceleration ) |
| Friction: | A contact force that resists the sliding motion of two surfaces that are touching. |
| Force: | What makes things move or change how they move. |
| Contact - Force: | A force that happens when two objects are physically touching each other. (Ex: Rubbing your hands.) |
| Acceleration: | A measure of the change in velocity during a period of time. |
| Reflection: | The bouncing of a wave off a surface. |
| Absorption: | The transfer of energy by a wave to the medium through which it travels. |
| Transmission: | The passage of a wave through a medium. |
