3
Q
What’s the centripetal force? Where is it always directed to?
A
The resultant force causing the acceleration, always directed to the centre of the circle
4
Q
What forces could provide the centripetal force?
A
Gravitational force, friction, tension
5
Q
How can you increase the centripetal force?
A
Increase the mass of an object, increase the speed of an object, decrease the radius of the circle
