Forces

In our Edgar Allan Poe Machine, there are 5 forces being used. We are using gravity and air resistance when we launch the penny into the air having both gravity pulling it down and air resistance slowing it from falling or opposing gravity. We have applied force when we hit the tee to make the tennis ball fall off the tee an down the ramp. We have friction when the toy train is rolling down the ramp and we have tension when the rope is being held tight waiting for the scissors to cut it.
