| Why Do Things Fall to Earth? (Gravity Explained!) | |
|---|---|
| Tip for Parents | Use these questions to encourage your child to explain what they have learned about gravity. Give them time to think, and allow them to give their own explanations, even if they aren't perfect. Help them by using simple examples and gentle prompts. |
| 1. What is gravity? | Gravity is the invisible force that pulls everything towards the centre of the Earth. It's the reason why things fall when you drop them. |
| 2. Who helped us first understand gravity? | Isaac Newton noticed that things always fall down and realised there must be a force pulling them. He called this force gravity. |
| 3. What would happen if gravity suddenly disappeared? | Everything would float away! People, cars, water, and even buildings could drift into space because nothing would be holding them down. |
| 4. Why is gravity weaker on the Moon than on Earth? | Because the Moon is smaller and has less mass (the amount of "stuff" something is made of). Less mass means less gravity pulling things down. |
| 5. Why don’t we notice gravity most of the time? | Because we are used to it always being there. It’s working all the time, pulling everything down gently but firmly, so it feels normal to us. |
| 6. What does gravity do in space? | It keeps the planets going around the Sun and the Moon going around the Earth. It also helps keep stars and galaxies together instead of drifting apart. |
| 7. Why do astronauts float when they are in space? | Because they are far from Earth's surface, gravity is weaker. They are also in free fall around the Earth, which means they fall but never hit the ground, making them float. |
| 8. How does gravity affect our everyday lives? | It helps us stay on the ground, makes things fall, helps rivers flow downhill, keeps buildings standing firmly, and makes sure food stays in our bowls instead of floating away! |
| 9. What is an orbit? | An orbit is when something, like the Moon or a satellite, is constantly falling towards a planet because of gravity but also moving sideways fast enough to keep missing and going around it instead of crashing into it. |
| 10. Can gravity ever go away? | No, gravity is always there, but it gets weaker the farther you go from a planet or star. Even out in space, there is still some gravity, just much less than on Earth. |
