Gravity
| Term | Definition |
|---|---|
| What is gravity? | the natural force that pulls everything downward toward the planet's center. |
| What are the 2 factors that affect gravitational force? | Mass and Distance |
| How does mass affect gravitational force? | The greater the size of the mass of objects, the greater the size of the gravitational force (pull between 2 objects) |
| The strength of gravity is equivalent to... | the distance between 2 objects. |
| What happens to gravitational attraction when the separation distance between 2 objects decreases? | it will weaken and decrease. |
| What is the difference between gravitational force and gravitational attraction? | pulls objects with mass toward each other the attraction between all masses |
| What is mass? | the measure of the amount of matter an object contains. |
| What is weight? | a measure of how strongly gravity pulls on something. |
| Does mass change when an object's location changes? | no |
| Does weight change based on an object's location or the amount of gravity it bears? | yes |
| What is the SI unit of mass? | kg |
| What is the SI unit of weight? | newtons |
| What is free fall? | the downward movement of something only influenced by the force of gravity. |
| What keeps orbiting objects in orbit? | gravity |
| Why do objects orbit each other? | gravity |
| Why do astronauts float in space? | their location |
| What affects the strength of the gravitational force between them and the Earth? | their location. |
| Is mass unchanging? | yes. |
| Is weight unchanging? | no. |
