Force has both magnitude and direction.
Sir,as said that vector quantities measure both direction as well as magnitude and scalor just me sure the direction so on what basis or from what terms these two names vector and scalor are derived
Observation 1: Try to stop a ball coming towards you,so as to save a boundary, by applying a force of some magnitude in the opposite direction of the motion of ball.
Observation 2: In this case apply the force of same magnitude but in same direction of the motion of the ball.
In observation 1 boy saves a boundary by applying a force opposite to the direction of motion but in observation 2, the change in direction of force cost the team 4 runs as the change in direction of force pushed the ball further to the boundary.
So, the change in effect of a force can be experienced by a change in it's direction as well as magnitude. The above statement is :-
A)Has force only magnitude or both direction and magnitude ?
B)What is necessary condition for a force to come into play?
C)on the basis of interaction what are the two categories of forces?
D)What should happen if there were no force of friction?Imagine and describe in your own words?
