Question

what is the force that causes centripetal acceleration when a car goes around curve?

Explanation:

Step1: Recall centripetal force concept

Centripetal force is the force that causes centripetal acceleration. When a car goes around a curve, the frictional force between the tires and the road provides the necessary centripetal force.

Step2: Analyze the options

• Gravity acts vertically downward.
• Normal force acts perpendicular to the surface (vertically upward in this case for a level road).
• Tension is a force in strings or cables, not relevant here.
• Friction is the force that can act horizontally towards the center of the curve to provide the centripetal force.

Answer:

Friction
