Circular Motion and Centripetal Force

Front

What is the cause of the outward motion of swings in a circular ride?

Back

Inertia

Front

What type of acceleration occurs when an object is in circular motion?

Back

Directional acceleration.

Front

True or False: The centripetal force of satellites is similar to gravitational force because they are both a net force towards the center of the Earth.

Back

True

Front

True or False: When an object is in circular motion, it is constantly changing its velocity.

Back

True

Front

True or False: If centripetal force stopped acting on all satellites, they would continue traveling in space in a constant direction and constant speed.

Back

True

Front

Define centripetal force.

Back

Centripetal force is 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 speed and centripetal force in circular motion?

Back

Centripetal force increases with the square of the speed of the object.

Front

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

Back

The object will move in a straight line at a constant speed due to inertia.

Front

What is the formula for centripetal acceleration?

Back

Centripetal acceleration (a_c) = v²/r, where v is the linear speed and r is the radius of the circular path.

Front

What is the direction of centripetal force in circular motion?

Back

Centripetal force always acts towards the center of the circular path.
