NEWTON'S FIRST LAW OF MOTION LAB 3-6
Newton's First Law: The law of inertia.
- 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
Newton's First Law of Motion:
- An object at rest will remain at rest unless acted on by an unbalanced force.
- If the object is moving at a constant rate, the unbalanced force that acts upon it will change its velocity.
- Examples: Rolling a marble across the floor. The marble eventually stops because of air resistance. It will only move if another force acts upon it.
- Examples: Kicking a soccer ball across the field, and it being stopped by the net, because of the unbalanced forces acting upon it.
STATION 1:
- When the car hits the marker, the force acts upon it, making the penny fall out.
- The car goes off track.
- The speed suddenly stops.
- When the seatbelt is used, the penny doesn't fall out, even when the force is acted up on it.
Answer: The band acts as a force to stop the penny from flying out.
STATION 2:
Results: 2 pennies.
Observation: The penny flies off.
Answer: When the penny stays still and the finger's force affects on it, the penny falls. It will fall if not caught by your hand.

STATION 3:
Flat surface:
It initially goes to 0.75 N and then settles at 0.50 N.
Sand paper:
It initially goes to 0.50 N then back to 0 N, when the block falls down.
Carpet: 050 N, then 0.25 N.
When the fore of the spring scale acts upon, the block moves. The higher the nutons, the farther it moves.
