Question

When a car turns a corner on a level road, which force provides the necessary centripetal acceleration? 1) gravity 2) normal force 3) air resistance 4) tension 5) friction

Answer 1

5.Friction

Step-by-step explanation:

A centripetal force is the type of force that is needed to keep a body along a circular path.

force is that which changes a body's state of rest or uniform motion in a straight line.

The centripetal force produces an acceleration (centripetal ). The force responsible is frictional force between the tyres and the road. It makes it keeps the force in the circular path.

From newton's second law of motion

F=ma

a=α^2r

α= angular velocity

r=radius from the center to the circumference of the road

Gravity is vertical. Tension is not involved during the motion.

Friction is the answer

Answer 2

5) Friction.

Step-by-step explanation:

The force that provides the necessary centripetal acceleration is the friction. The centripetal acceleration must be horizontal, directed to the center of the circular trajectory. Gravity and normal force are vertical, air resistance is against the speed of the car (not towards the center of the trajectory) and there is no tension in this example.
