The correct answer to the question is unbalanced .
EXPLANATION:
As per Newton's first laws of motion, we know that a body at rest will be at rest or a body moving with uniform velocity along a straight line will keep on moving with the same velocity along that line unless and until it is compelled by some external unbalanced forces acting on.
Hence, it is the unbalanced force which is responsible for creating the motion on the body.
As per the question, Anne applied some force on the toy car. It is called applied force. There is also frictional force between car and the surface which opposes the motion of the car. The toy car will move due to the net force acting on it. The net force is known as unbalanced force.
Answer:
The correct option is "unbalanced forces".
Explanation:
It is given that, Anne applies a force on a toy car and makes it move forward. On the application of force, the car is moving in forward direction. This shows there must be a frictional force acting in opposite direction. Here the forces acting on it are balanced.
If the object does not move at all, then the forces will be balanced. As the forces are equal and opposite in nature . So, they cancel out each other.
So, the correct option is (d) " unbalanced ".
