Object At A Distance
Quiz
| Question | Answer |
|---|---|
| Attract | To exert a force that draws something in |
| How to build an electromagnet | Metal rod, wire, battery |
| Is gravity a force? | Gravity is a force because a force is a push or a pull |
| Gravity | Is a force that is either a push or a pull |
| Magnet | Can attract or repel items |
| Mass | Is the amount of matter in an object |
| Negative and Positive | When two of the same type are put together they repel or push away Negative = North Positive = South |
| Repel | To Push back or away by a force |
| Weight | A measure of the amount of gravity pulling on an object and is measured in pounds |
| What are the characteristics of electromagnetism? | The strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it |
| How are mass and weight different? | Mass is the actual amount of material contained in a body and it always stays the same Weight is the force exerted by the gravity on that object and it can be different |
| What determines how much gravity an object has? | Mass and Distance determine how much gravity an object has. |
| How do positive and negative objects interact? | When two of the same types are put together, they repel or push away. When two opposites are put together, they attract. |
| How is gravity affected by distance? | Mass: As mass Increases, gravity increases The more mass an object has, the more gravity that acts on that object |
| How is gravity affected by mass? | Distance: As distance increase, gravity decreases The larger the distance, the less gravitational force each object exerts on the other. This means that the closer one object is to another, the more gravity acts on that object. |
