What is net force explain with an example

Net force is the vector sum of forces acting on a particle or body. ... Its associated torque, the net force, becomes the resultant force and has the same effect on the rotational motion of the object as all actual forces taken together. It is possible for a system of forces to define a torque-free resultant force.

Explanation:

In a tug of war, a fat man pulls with a force of 100 N on one side, and a man pulls with 90 N on the other side. Compute the net force.

Solution:

Given:

Force F1= 100 N,

Force F2 = -90 N.

The net force formula is given by,

F_NET = F_1 + F_2F  

N

ET=F  

1

+F  

2

F_NET = (100 ) +(– 90)F  

N

ET=(100)+(–90)

F_NET= 10 NF  

N

ET=10N

Therefore, the net force is 10 N.
