Question

A moving car engine is turned off, and slowly comes to rest . is the force acting on it balanced or nbalanced ? name the force ?

Answer 1

The force is unbalanced because if the force will be balanced then there is not any effect on the car and so it will not stop.
The force is frictional force

Answer 2

Now then let me explain.

-we know that in the state of a balanced force the object stays till or keeps moving with a uniform speed as two forces are acting towards the object in two opposite directions.

-it is said that the car comes to rest so it does not fall in the category of balanced force. So the force acting is unbalanced force.

-the force that makes the car stop is frictional force between the road and the tires.
