Question

You are pushing on a heavy door, trying to slide it open. If your friend stands behind you and helps you push, how have the forces changed?
a. The net force applied will increase.
b. The net force will decrease.
c. There will be less friction.
d. The applied force does not change.

Answer 1

A...... The net force applied will increase.

Answer 2

Answer: A) The net force applied will increase.

Explanation:

Both of us trying to push the door will increase the net force and this is because the force is been applied by both of us in the same direction. Forces acting in the same direction are added up to produce a resultant force which will cause an increment in the total force.
