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 the ball.
Observation 2: In this case apply the force of the same magnitude but in the same direction of the motion of the ball.
In observation 1, the 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 the effect of a force can be experienced by a change in its direction as well as magnitude. The above statement is:-
True
In the above two observations, it is clear that if you change the direction of force, it results in extra four runs. Hence, we can conclude that even if we only change the direction of the force, we can get different results.
