Step-by-step explanation:

A car is pushed using a force of 400 N. If the car starts moving in the direction of application of force. This is a example of unbalanced force as the object which was in rest started moving because of the application of balanced forces.

Forces are mainly of two type,

1) Balanced force

2) Unbalanced force

Balanced force

Balanced Force => If the resultant of applied force is equal to zero then the forces is equal to balanced forces.

Example: In the tug of war if  both  the teams apply similar magnitude of forces in opposite directions, rope doesn’t move in either side. This happens because of balanced forces where resultant of applied force become zero.

Balanced force do not cause any change of state (motion and rest) of an object, they are equal in magnitude and opposite in direction.

Balanced forces can change the shape and size of an object. For example: when force are applied both sides over a balloon, the size and shape of balloon is changed

Unbalanced force

Unbalanced Force => If the resultant of applied force is not equal to zero then the forces is known as unbalanced forces, the object which was in rest can be move because of applying force.

Example: Ball moves from one place to another after kicking it. This is an example of unbalanced force.

Unbalanced force can :-

move a stationary object

increase or decrease the speed of a moving object

stop a moving object

change the shape and size of the moving object.

Answer

When the car is pushed with a force of 400 N and if the car is moving, then it is called as an unbalanced force

━━━━━━━━━━

Explanation

• So here we are given that the body is moving and is it was a balanced force the body would not have moved a bit and the statement would have become invalid

• Am unbalanced force is a kind of force where the force that acts on a direction is greater than the opposing force

• Force > Opposing force

• Here 400 > Opposing force

• In a balanced force the opposing direction will be equal to the direction in which we push such that the forces cancel each other and there is no displacement, in these cases there will also be no work done

• Force = Opposing force
