Circular Motion

Front

Centripetal force means

Back

center seeking

Front

Centripetal force and acceleration always point

Back

towards the center of the circle

Front

This pulls the satellite towards the earth and keeps it in orbit.

Back

gravity

Front

Anytime an object is travelling along a circle, it is accelerating.

Back

True

Front

Centripetal force of an object moving in circular path is directed

Back

towards the centre

Front

What is the formula for centripetal acceleration?

Back

a_c = v^2 / r, where v is the tangential speed and r is the radius of the circle.

Front

What is the relationship between centripetal force and mass?

Back

Centripetal force (F_c) is directly proportional to mass (m): F_c = m * a_c.

Front

What is the role of friction in circular motion?

Back

Friction provides the necessary centripetal force to keep an object moving in a circular path.

Front

What happens to the centripetal force if the speed of the object increases?

Back

The centripetal force increases as the square of the speed increases.

Front

What is the effect of increasing the radius of the circular path on centripetal acceleration?

Back

Centripetal acceleration decreases as the radius increases, given constant speed.
