Centripetal Force and Circular Motion Quiz

What is the direction of the centripetal force acting on an object moving in a circle?

• Outward from the center

• Inward towards the center

• Tangential to the circle

• Perpendicular to the plane of motion

According to Newton's first law of motion, what happens to an object in motion if no unbalanced force acts on it?

• It will eventually stop

• It will accelerate

• It will continue in a straight line at constant speed

• It will move in a circular path

What provides the centripetal force for a car making a turn on a flat road?

• Air resistance

• Tension in the tires

• Friction between the tires and the road

• Gravity

Why does a passenger feel pushed outward when a car makes a sharp turn?

• Due to an outward force acting on them

• Because of the car's acceleration inward

• Because of their inertia resisting the change in direction

• Due to the gravitational pull

What happens to the speed of an object in uniform circular motion?

• It fluctuates

• It increases

• It decreases

• It remains constant

What is the role of friction in circular motion of a car?

• It opposes the centripetal force

• It decreases the speed of the car

• It increases the speed of the car

• It acts as the centripetal force

Which of the following is NOT an example of centripetal force?

• Tension in a string of a swinging bucket

• Friction in a car's tires during a turn

• Gravity acting on a satellite

• Air resistance on a moving car

What is the effect of a centripetal force on an object's velocity?

• It decreases the velocity

• It changes the direction of the velocity

• It increases the velocity

• It changes the magnitude of the velocity

What is the sensation of being pushed outward in a turning car actually due to?

• Gravitational force

• An outward force

• Inertia of the passenger

• Centripetal force

In the context of circular motion, what does the term 'centripetal' mean?

• Center seeking

• Center fleeing

• Perpendicular

• Tangential
