Slide 2: 

What is gravity??

Slide 3: 

Gravity is a force of attraction between objects because of their masses.

Slide 4: 

Gravity is a result of mass. So, all matter experiences gravity. All matter has mass.

Slide 5: 

Gravity is occurring all around society. Gravity is helping us to stay on the ground. This is why when we jump gravity pulls us back to the ground.

Slide 6: 

A British scientist by the name of Sir Isaac Newton created the law of gravitational force on a summer night while observing an apple falling from a tree. The law states that all objects in the universe attract each other through gravitational force and that the size of the force depends on the masses of the objects and the distance between them.

Slide 7: 

If the masses are small than the gravitational force is small.

Slide 8: 

The farther the distance, the gravitational force decreases. If the mass increases, the gravitational force increases.

Slide 9: 

Weight is the force created by the gravitational force exerted on an object.

Slide 10: 

A measure of gravitational force is weight. Did you know that weight could also be a measure of gravitational force exerted on objects by other planets and the moon?

Slide 11: 

Weight is measured with a spring scale. A balance is what is used to measure mass. Remember that mass and weight are different!

Slide 12: 

Since gravitational force is around the same every where on earth, the weight of an object is about the same anywhere.

Slide 13: 

Thanks to gravity, we are still on earth and are not floating everywhere.
