What is gravity?
Gravity is a force that pulls objects towards one another. The objects do not have to be touching.
Anything that has mass has a gravitational pull.

Anything that has mass has a gravitational pull.
Mass is a measure of the amount of matter that an object is made of. Mass is measured in kilograms.
Anything that has a mass is affected by gravity. There is a gravitational pull between the Sun and the planets in our solar system, between the Earth and us, and even between two ants!
A dropped object falls to the ground because it is pulled down by the force of gravity that Earth exerts on the object.
In 1687, an English scientist called Isaac Newton published his theory of gravity. He discovered that the more mass an object has, the greater the pull, or force, that is exerted on it.
The force of gravity is also dependent on the distance between two objects - the further apart they are, the weaker the pull between them is.

According to the National Curriculum Science objectives, children should learn about gravity in KS2. It is assigned as compulsory learning in Year 5 under the 'Forces' strand of learning.
