Topic 6.1: Circular Motion Flashcards
1
Q
What happens to force when acceleration is 0
A
Newton’s Second Law of motion says for zero acceleration that there is no net or resultant force
2
Q
What is the relationship between velocity and force in circular motion?
A
The force acts at 90° to the velocity so there is no force component in the direction of velocity
As a result, the magnitude of the velocity is constant
However, the direction of the velocity changes
3
Q
What is the angular displacement
A
The change in angle, in radians, of a body as it rotates around a circle
4
Q
What is angular speed
A
The rate of change in angular displacement with respect to time
