La fuerza centrípeta

What force is responsible for keeping an object moving in a circular path?

• Magnetic force

• Centripetal force

• Gravitational force

• Frictional force

According to Newton's first law, what happens to an object moving in a straight line if no external force acts on it?

• It will eventually stop

• It will change direction

• It will accelerate

• It will continue moving in a straight line

What is the term for the resistance of an object to change its rotational speed?

• Centripetal force

• Moment of inertia

• Angular momentum

• Torque

Why do skaters spin faster when they pull their arms in?

• Their moment of inertia decreases

• Their axis of rotation changes

• Their mass increases

• They apply more force

What provides the centripetal force that keeps satellites in orbit around Earth?

• Magnetic force

• Frictional force

• Gravitational force

• Electromagnetic force
