Force and Gravity                                                                          
When cars go down hill they have more force than cars going up hill because it has more weight going down hill. A car going down hill moves really fast and doesn't need much force because its going down hill. Cars need lots of force to go up hill because gravity is pulling them back down and it wants to go up instead. 

When you drop something the gravity pulls it towards the center of the earth or the ground so what goes up has to come down. It falls down without a push or pull.
