Question

If you are pushing on a door trying to make it slide open if your friend stands behind you and helps you push how hase the forces changed

Answer 1

The force will change as the net force applied will increase.

Step-by-step explanation:

If you are pushing on a door really hard, trying to make it slide open and if your friend is also stand behind you and contributes to help you push towards the door, then the overall force will change as the net amount of force applied will increase.

This is an example of Newton's second law according to which you need more force to move an object with heavier mass.

F = ma

Therefore, the force applied by you and your friend will add and the net force applied will be increased.

Answer 2

The net force applied will increase

Explanation

According to Newton’s second law , force is the product of mass and acceleration. In this case, when a friend joins in the pushing of the door, the total net force applied on the door increases and the door will open with much ease. Force=mass × acceleration,

F=m × a
