What is gravity?

Gravity is a force that describes not two objects attract one another.

Mass v WeightWhat is Mass?

Mass how much stuff is in an object.

In physics, we use kilograms, or kg.

Then what is weight?

Weight depends on the strength of gravity.

If the object is heavier, it has more gravity force.

This is why we weigh less on the moon.

The moon is less massive, so the force of gravity is smaller.

Even though we have the same amount of stuff, or mass, it feels different because the gravity is different.
