NEWTONS LAWS

• 1st Law: Law of Inertia; when the marble is moving, it won't stop until the end of the track
• 2nd Law: Equation Law; the force acting upon the marble is gravity.
• 3rd Law: Action-Reaction Law; the force of gravity allows the marble to have enough speed to go through the loops and over the hills.

GRAVITY

• Gravity plays an important role in the movement of the marble. As soon and the marble is dropped from the top of the track, gravity does the rest.

FORCE (CENTRIPETAL)

• Centripetal force is the circular force. The mass of the marble also affects how fast it goes. The mass of the marble is .00515kg.

FRICTION TYPES

• The type of friction that is occurring is rolling friction.
• When the marble stops, static friction is occurring.
