Centripetal Motion

Front

What keeps an object like the moon in centripetal motion?

Back

Gravity

Front

Describe the motion of a ball when the string breaks while swinging it in a circle.

Back

It moves in a straight line at a tangent to the circle.

Front

What keeps the water in a bucket when swung in a circle?

Back

Inertia

Front

What does the term 'centripetal' mean?

Back

Center seeking.

Front

Calculate the acceleration of Bruno the bat flying at 0.5 m/s in a circle of radius 1 m.

Back

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 formula for centripetal acceleration?

Back

Front

Explain the role of gravity in centripetal motion.

Back

Gravity provides the necessary centripetal force to keep celestial bodies in orbit.

Front

What happens to an object in circular motion if the centripetal force is removed?

Back

It will move in a straight line at a constant speed, following Newton's first law of motion.

Front

What is the difference between centripetal and centrifugal forces?

Back

Centripetal force is an actual force directed towards the center, while centrifugal force is a perceived force that appears to act outward on a mass moving in a circular path.
