Front

Why do objects experience centripetal acceleration?

Back

Because they are constantly changing direction and the net change is directed inward.

Front

What force keeps an object moving in a circle?

Back

Centripetal force (inward).

Front

Centripetal acceleration acts __________ of the circular path.

Back

Towards the center.

Front

What is the equation for centripetal force?

Back

F = mv²/r.

Front

What is T (period)?

Back

The amount of time it takes to complete one circle.

Front

Define centripetal force.

Back

The net force that acts on an object moving in a circular path, directed towards the center of the circle.

Front

What is the relationship between centripetal acceleration and velocity?

Back

Centripetal acceleration increases with the square of the velocity.

Front

What happens to centripetal force if the radius of the circular path increases?

Back

Centripetal force decreases if the speed remains constant.

Front

What is the formula for centripetal acceleration?

Back

a = v²/r.

Front

Explain the concept of centrifugal force.

Back

Centrifugal force is an apparent force that acts outward on a body moving around a center, arising from the body's inertia.
