newton's laws of motion
1st Law: An object at rest will remain at rest or an object in motion will remain in motion unless an unbalanced force acts on it.

Station 4: pg 106 notes:
- an object moving at a constant velocity will continue moving at a constant velocity unless acted on by an outside unbalanced force.
- an object will stop if a physical object does not act on it because other unbalanced forces like air resistance and friction will slow the object down
- air resistance is the friction experienced by an object moving through the air
- friction is the force that two surfaces exert on each other when they rub against each other
- MY EXAMPLE: When you roll a tennis ball on the floor, and you just let it roll, the tennis ball will stop eventually because air resistance and friction were slowing the ball down the entire time it was rolling on the floor you just sent it down.
Station 1:
When the penny was not attached to the car, every time it hit the marker, the car would stop, and the penny would fly to the bottom. When the car missed the marker and the penny was unattached to the car, the penny would stay on the car and fly to the bottom with the car. When the penny was attached to the car with a rubber band the penny stayed on the car the entire time and stopped moving with the car. This activity models Newton's first law of motion because when the penny was not attached to the car, the marker would not stop the penny from moving, so it would continue.
Station 2:
Best record: 2 pennies
The penny falls down with the card
The object not in motion moves when I hit it.
Station 3:
Normal Floor:
Initial high reading: 10 grams
Steady speed reading: 3 grams
Sand paper:
Initial high reading: 200 grams
Steady speed reading: 130 grams
Carpet:
Initial high reading: 50 grams
Steady speed reading: 30 grams
