- An object at rest will remain at rest or an object in motion will remain in motion unless an unbalanced force acts on it. (causes acceleration)

Station 2
It represents Newton's First Law of Motion by showing that when an object is at rest, it will stay at rest. If you flick the paper from under the penny, the paper doesn't provide enough friction to move the penny, so it will fall into the cup. When you flick the penny off of your forearm, an unbalanced force acts upon it until your hand is their to catch it acting like an unbalanced force.
Station 3
250 Max and evens out at 200 on sandpaper
100 Max and evens out at 50 on back of sandpaper
Due to the sandpapers friction, it shows that it takes much more force to pull the block on sandpaper than on the back of the sandpaper. The sandpaper require more force, and the back require less force.
Station 4
friction is a force that two surfaces exert on each other when they rub against each other. Air resistance is the friction experienced by an object moving through the air.
example: put a block on the ground. the block doesn't move because there are no forces acting on it. But, when you push the block, a force makes it an unbalanced force.
Station 5
The object is in motion because of the force that is gravity pushing it down the ramp. The marker is the unbalanced force which acts on the penny to stop it. Without the penny, the car has less force acting upon it
