|---|---|---|---|---|---|
| The force that attracts all objects toward each other. | Gravity
🗑
|

| The force of gravity on an object. | Weight
🗑
|
||||
| This states that every object in the universe attracts every other object. | Law of universal gravitation
🗑

| The strength of the force of gravity depends on two factors:___________________ and ___________________. | Mass and Distance
🗑
|
||||
| The amount of matter in an object. | Mass
🗑
|
||||
| If mass increases, gravity __________________. | Increases
🗑
|
||||
| The tendency of an object to resist a change in motion. | Inertia
🗑
|
||||
| This states that an object at rest will stay at rest and an object in motion will stay in motion with a constant speed and direction unless acted on by a force. | Newton's First Law of Motion
🗑
|
||||
| If distance increases, gravity _____________________. | Decreases
🗑
|
||||
| These two factors combine to keep the Earth in orbit around the Sun and the Moon in orbit around the Earth. | Gravity and Inertia
🗑
|
||||
| If mass decreases, gravity _________________. | Decreases
🗑
|
||||
| What would happen to your weight if you traveled to a planet that has a greater mass than Earth? | Your weight would increase
🗑
|
||||
| If distance decreases, gravity ______________________. | Increases
🗑
|
||||
| What would happen to your mass if you traveled to a planet with a smaller mass than Earth? | Your mass would stay the same
🗑
|
||||
| If the mass of Earth suddenly doubled, what would happen to the gravitational force of Earth? | The gravitational force would also double.
🗑
|
||||
| What would happen if the Sun suddenly disappeared from our solar system? | The planets would fly off through space in straight lines.
🗑
|
||||
| What would happen if the Earth lost inertia? | It would fall into the Sun.
