We can jump higher on the moon because:

• The Earth has less mass.

• The moon's gravitational pull is greater.

• The moon's gravitational pull is weaker.

• The Earth has less gravitational pull.

What is gravity?

• a star and all the objects that revolve around it

• a picture or shape created by a group of stars

• a force that pulls objects toward its center

• a force that makes objects drift apart

When you increase the size of the Earth and the Sun what happens to the gravity?

• the gravity of both Earth & Sun increases

• the gravity of the Earth & Sun decreases

• no one is sure because you cannot increase the size of the Earth & Sun

• all of the above

What happens to the gravity when you move the Sun & the Earth far away from each other?

• nothing happens everything stays exactly the same

• the gravity of the Earth and the Sun increases

• no one knows because it is impossible to move these objects

• the gravity of the Earth and the sun decrease

What is weight?

• the amount of mass within an object

• the measure of gravity pulling on an object

• no one knows

• the amount of pounds it says when you step on the scale

If the mass of the Sun increased what would happen to the amount of gravity it exerts?

• nothing would happen

• it will decrease

• it will stay the same

• it would also increase

Which is NOT true about mass?

• it is the measure of the amount of matter within an object

• it is constant, meaning it stays the same no matter where you go

• it is measured in Kilograms

• it is a measure of the pull of gravity
