Force and Motion

How it works?

Imagin

Imagin that your in a hockey game and you hit the puck all the way from your goal to the other teams goal. What caused that was two forces working togher, it was the push of the stick, and hardly no firction on the ice.  

Gravity

Gravity is the force that keeps us on the ground. An example would be an object being droped and falls to the ground, the force that makes the object fall is gravity.
