Question
State two effects of a force when applied on a body.
Advertisements
Solution 1
Two effects of applied force:
- It can change the state of body.
i.e. It can stop a moving object and also a force can move a stationary object. - A force can change the shape (and size) of an object.
Solution 2
-
Change in Motion:
- A force can make a stationary body move or change the speed and direction of a moving body.
- Example: Pushing a stationary car causes it to start moving.
-
Change in Shape or Size:
- A force can deform an object, altering its shape or size.
- Example: Squeezing a rubber ball changes its shape temporarily.
