Question
A man tries to pull a heavy load but is not able to move it. How can he make the load move?
- By decreasing the force applied on it
- By increasing the force applied on it
-
By applying force in another direction
- None of the above
Hint:
If the force is applied in the direction of the motion, it will increase the speed of the moving body. However, if the force is applied in the direction opposite to that of motion, it will decrease the speed or may even bring the moving body to rest.
The correct answer is: By increasing the force applied on it
- The effect of an applied force can be different as it also depends on the direction of the applied force. If the force is applied in the direction of the motion, it will increase the speed of the moving body. However, if the force is applied in the direction opposite to that of motion, it will decrease the speed or may even bring the moving body to rest.
- Here we have to move the body so we have to increase the applied force so that it can move.
