What do you think life would look like if there was no gravity? Let’s discover five glorious gravity facts for kids.

Gravity Facts for Kids Fact Number 1: An Object’s Mass Will Depend on How Much Gravity It Has

The bigger an object’s mass, the more gravity it will have, while objects with a smaller mass will have less gravity. Black holes have the strongest gravitational pull in the entire universe. Black holes are some of the most destructive objects in the universe. At the centre of our galaxy is a massive black hole which has the biggest mass in the universe. Mass is made up from how many atoms are in an object. The mass of an object never changes. The gravitational pull of black holes is so strong, even light cannot escape it.

Gravity Facts for Kids Fact Number 2: Sir Isaac Newton Discovered Gravity

You have probably heard of Sir Isaac Newton before but did you know that he discovered gravity by chance? The tale is told that Newton saw an apple fall straight out of a tree and hit the ground in 1666. The apple fell straight, not left or right. He realised that a force made this occur and he named this force gravity. Sir Isaac Newton was one of the greatest mathematicians in the world and his work influenced many other great scientists such as Albert Einstein.

Gravity Facts for Kids Fact Number 3: Ocean Tides Are Caused by The Gravity of The Moon

Gravity makes everything in the universe pull on each other. It works on ocean tides by making the Moon pull on the Earth, when this happens the seas and oceans water moves. As the Earth rotates, the water in our seas and oceans will build up on the side closest to the Moon. This is why we have high and low tides. If gravity didn’t exist then the Moon wouldn’t orbit the Earth and the Earth wouldn’t orbit the Sun.

Gravity Facts for Kids Fact Number 4: Gravity Keeps Us Here on Earth

Without gravity we wouldn’t be standing here on Earth. We would have to be tied to the ground otherwise we would float up into the air and space. There is very little to no gravity in space. This is why astronauts float around in space and in their spaceships.

Gravity Facts for Kids Fact Number 5: Gravity is Shrinking Us Everyday!

Did you know that gravity actually makes us smaller? You are taller in the morning than you are at night. Although the difference isn’t huge or noticeable, it is still a difference. Gravity pulls us to the ground which causes our spines to slightly shrink. When we sleep we are lying down, allowing our spine to stretch to its original size. Astronauts can actually grow in space as there is no gravity. Measure yourself first thing in the morning and then again at night and see just how much gravity shrunk you throughout the day.

We hope you enjoyed learning more things about gravity as much as we loved teaching you about it. Now that you know how majestic this gravity is, you can move on to learn more about STEM like: Electricity, Electromagnetic Waves and Circuits.
