Gravity and Forces — Fun Science
Gravity is an invisible force that pulls everything towards the ground — it is the reason things fall down and not up!
Learn
- Gravity is a pulling force. The bigger something is, the stronger its gravity.
- Earth is very large, so its gravity is strong. It pulls everything towards its centre.
- Gravity is what keeps the Moon orbiting the Earth and the Earth orbiting the Sun.
- In space, far from large objects, there is very little gravity. That is why astronauts float.
Try These Questions
- What does gravity do?
Answer: Pulls things towards the ground
Hint: Think about what happens when you drop a ball. - Why is Earth's gravity strong?
Answer: Because it is very large
Hint: Bigger things have stronger gravity. - What keeps the Moon going around the Earth?
Answer: Gravity
Hint: The same force that pulls things down here.
Gravity Drop Test
- Find two small objects of different weight — for example, a small ball and a feather.
- Hold them at the same height and drop them at the same time.
- Watch which one lands first and write down what you notice.
- Now try two objects that are the same size but different weights. Record your results.
Safety: Use small, soft objects. Do not drop anything breakable. Ask an adult if you are unsure.
