Gravity by Year 4 Rhydypenau

Gravity is a force that keeps you on the ground, though you can't see it it's still there.

Something attracting something else is happening because of a force called gravity. Gravity keeps planets orbiting around the sun. The moon has only one sixth of the Earth's gravity. Gravity affects all objects and gives them their weight. The more mass an object has, the heavier it weighs. If you dropped a brick and a feather on Earth the rock woulds land first. This is because although gravity pulls them both toward the Earth with the same acceleration, there is air resistance which acts against the pull of gravity.

The Earth pulls everything into the centre of it. The Earth is so huge and has lots of mass that its gravity is then strong enough to pull everything towards its surface.

Isaac Newton

Isaac Newton discovered gravity in 1687. Many people say an apple dropped on his head and he started wondering about how the apple had fallen. He did many scientific experiments to find out what had caused the apple to fall on his head. The Earth pulls everything to the centre.

If you dropped a brick and a feather at the same time on the moon they would fall at the same speed because there is no air. Gravity is a strong force. The greater the object's mass the greater its weight. Gravity keeps planets in orbit. The moon has one sixth of the Earth's gravity. Loose balance(=fall over)gravity pulls you towards the earth. Gravity is also called gravitation. Gravity keeps planets orbiting the sun and keeps stars together in the galaxies. The moon has 1/6 of the earth's gravity.
