For a vehicle moving on a curved path the centripetal acceleration is provided by the:
Correct answer: D. Force of friction
- A. Air pressure
- B. Engine
- C. Shape of the wheels
- D. Force of friction
Explanation
The centripetal force required for a vehicle to move on a curved path is provided by the force of friction between the tires and the road. This force acts towards the center of the circle, allowing the vehicle to maintain its curved trajectory. Other options such as air pressure, engine, and wheel shape do not directly contribute to this specific force needed for centripetal acceleration.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
