Explain with the help of examples that force has magnitude as well as direction
Answers
Force can be Simply called as a push or pull. So obviously, pushing and pulling are in different directions and have different effects when applied on a body.
When two forces act in same direction, the resultant force is the sum of the two forces acting in same direction . When two forces act in opposite directions, then the resultant force is the difference of the two forces acting in the direction of higher magnitude force.
For example:-
Your car stops in mid way. You start pushing your car from back applying some force. It is hard for you. Then another men joins you and pushes the car in the same direction. Now the resultant force is the sum of forces applied by both of you and the car moves forward.
In the same case, if the another men is against you, and pushes the car from front, then the direction of forces are opposite to each other. So the resultant force is the difference of the two forces. Now, the car will either stand still if two forces are equal
(difference is zero so magnitude of force is zero) or it will move in the direction of men who is applying more force(magnitude>0).
