Determining the Force Normal on a Toy Car moving up a Curved Hill

The video tutorial explains a physics problem involving a toy car moving up a semicircular hill. It covers the problem statement, clarifies the angle of the hill with the horizontal, and uses a free body diagram to analyze forces. The tutorial then solves for the normal force using physics equations and concludes with key points about the problem's dynamics.

What is the mass of the toy car used in the problem?

• 0.89 kilograms

• 0.453 kilograms

• 32 kilograms

• 1.15 kilograms

How does the angle of the hill relate to the car's position?

• It is irrelevant to the car's position.

• It increases as the car moves up.

• It remains constant.

• It decreases as the car moves up.

What is the direction of the normal force in the free body diagram?

• In the tangential direction

• Opposite to the force of gravity

• Perpendicular to the hill

• Parallel to the hill

Which force needs to be broken into components for analysis?

• Normal force

• Force of gravity

• Frictional force

• Centripetal force

What is the formula for centripetal acceleration used in the problem?

• Mass times acceleration due to gravity

• Mass times tangential velocity

• Tangential velocity squared divided by radius

• Tangential velocity divided by radius

What happens to the normal force as the car moves up the hill?

• It becomes zero

• It increases

• It decreases

• It remains constant

Why does the tangential velocity of the car decrease as it moves up the hill?

• Due to an increase in gravitational force

• Because of air resistance

• As a result of the incline angle increasing

• Because the car is accelerating
