Question
On which factor does the centripetal force not depend?
- Object’s mass
- Object’s shape
- Object’s speed
- Distance between the object and the axis point
Hint:
A centripetal force is a force that makes a body follow a curved path.
The correct answer is: Object’s shape
Three factors which affect the centripetal force are: mass of the object; its speed; the radius of the circle.
