Textbook Question
Chapter 4, Problem 1CQ
When a car accelerates starting from rest, where is the force applied to the car in order to cause its acceleration? What object exerts this force on the car?
Expert Solution & Answer
To determine
The location where the force is applied on a car in order to cause acceleration and the object that exert this force on the car.
Answer to Problem 1CQ
The force that causes the acceleration is applied at the wheels of the car and it is provided by the surface of the road.
Explanation of Solution
Frictional force between the wheels and the road is responsible for the movement of vehicles on road. The force of friction is acting in the backward direction so that as a reaction, the vehicle moves in the forward direction.
A surface with considerable value for the coefficient of friction offers required force of friction needed for the forward motion of the car.
The car accelerates from rest due to the friction between the wheels and the road and it enables the car to move forward. The force of friction is applied on the wheels of the car by the surface of the road.
