What is force?
Force is characterized in physics as the push or pull on a mass artifact that tends to cause rotation velocity.
Force is an external agent that can modify the state of rest or motion of a specific body. It has a magnitude as well as a direction.
The external entity that causes motion is force. There are two types of forces namely contact forces and non-contact forces.
The total amount of all the forces acting on an object is defined as the net force.
A mass can be accelerated by net force. Another force acts on a body at rest or in motion. When there are a large number of forces in a system, the net force is used.
In the given scenario, as boy is pushing on a heavy door, trying to slide it open and his friend stands behind him and helps him push this will increase the net force applied.
Thus, the correct option is A.
