Answer 1

1st roman

1) When we are walking, two force acts against each other. 2) when a car is driving

1.

The total sum of forces acting on a body is known as net force. Eg. If the wheels of a car push it with a force of 5 newton and drag it 3 newton the net force is 3 newton

3.

the inertia of the body is greater than the force applied therefore the body can not move with 2N force and it is at rest. the 2N force is gravitational force not an external force so that it can be in motion .
