A brief description of gravity.

1. The stuff that makes us stay on the ground Gravity

2. Once upon a time… This man was sitting under an apple tree. And….

3. Newton OUCH!!! “I know why that happened! It was Gravity!”

4. Newton’s Law Every large object exerts a force on another object

5. Force Gravity is a force that is exerted on us by the earth. This is due to the weight and mass of the Earth

6. Equation! Force = mass x acceleration

7. Constants 32 feet/second 9.8 meters/second

8. Example There is an object being dropped from 10 meters high with a mass of 22 kg

9. Don’t freak out! This equation ain’t so bad! Just plug in what you know…. And BOOOM! You’ve got it!

10. solution F = 22 kg x 9.8 meters/second F = 215.6 Newtons We did it!
