New cards

Define Centripetal Force.

Force which prevents a whirling object from leaving its circular path. Always directed toward the centre of rotation of the rotating object (also known as centre seeking force)

2
New cards

Centripetal forces always act in which direction?

Toward the centre of rotation of the rotating object

3
New cards

What is an alternative name given to centripetal force?

Centre seeking force

4
New cards

Centripetal forces are associated with which acceleration?

Angular acceleration (radial component)

5
New cards

The magnitude of centripetal force is most influenced by which property?

Most influenced by angular velocity

6
New cards

Define Centrifugal Force.

Reaction force to centripetal force (Newtons 3rd law)

7
New cards

Centrifugal forces always act in which direction?

Always directed away from the centre of rotation of the rotating object

8
New cards

What is an alternative name given to centrifugal force?

Centre fleeing force

9
New cards

Can either centripetal or centrifugal force exist without the other?

No
