It means size of the force

It is sum of all forces acting on a body.



If 2 forces act in same direction,

Magnitude of force increases

It is the sum of of both forces

 

If 2 forces act in difference direction,

Magnitude of force is the difference of both forces



Example 1 -If 2 forces act in same direction,

Suppose 2 persons are pushing car from back

Person 1 exerts force of X

Person 2 exert force of Y

Total Force exerted on car = X + Y






Example 2

If 2 forces act in difference direction,

Magnitude of force is the difference of both forces

 

Suppose 2 persons are pushing car one from back other from front

Person 1 exerts force of X

Person 2 exert force of Y

Total Force exerted on car = X - Y
