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 different direction,
Magnitude of force decreases
It 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 different direction,
Magnitude of force decreases
It 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
