Slide 1

Gravity

What is it?

Slide 2

Gravity is…

A natural force that pulls all objects toward the center of the earth.

Slide 3

What is a force?

A pull or a push on an object

Slide 4

Which do you think would fall first?

A bouncy ball

Or a marble

Try It!

Slide 5

They fall at the same rate of speed, but the marble has more mass (weight) and so gravity makes it fall harder! Gravity has a stronger force on things with more mass!

Slide 6

It takes a force to overcome gravity!

Throw a bean bag in the air

and then…

Throw a basketball in the air.

Which one was harder to throw?

Slide 7

You had to use more force to throw the basketball because it has more mass (weight)
