Circular Motion Flashcards
1
Q
How does Newton’s 1st Law apply to circular motion?
A
An object in motion or at rest will remain in motion or at rest until acted on by an external unbalanced force:
1. The force is required for an object to change direction towards the center of the circle instead of straight (centripetal force)
2
Q
How does Newton’s 2nd Law apply to circular motion?
A
An object will accelerate in the direction of the force:
1. The force must be towards to center of the circle
2. The object will accelerate towards the center of the circle
3
Q
How does Newton’s 3rd Law apply to circular motion?
A
Every action force has an equal and opposite reaction force
4
Q
What does friction do to centripetal force?
A
Friction increases the Fc which in turn increases the velocity
