Explain what happens when some children try to push a box on a rough floor?
pls give explanation relate to unbalanced force and in 30-60 words
Answers
If they push the box with a small force, the box does not move because of friction acting in a direction opposite to the push. This friction force arises between two surfaces in contact; in this case, between the bottom of the box and floor as rough surface. It balances the pushing force and therefore the box does not move.
Unbalanced Force
A force where two forces acting in opposing directions on a body, are not equal in magnitude and in size, is known as an unbalanced force. In an unbalanced force, a body changes its position i.e. we can observe a moving object changing its direction, either increasing the speed or decreasing the speed and a body at rest starts to move and vice versa.
Examples :-
- Ball moves from one place to another after kicking it. This is an example of unbalanced force.
- One person significantly heavier than the other creates a condition of unbalanced force in a seesaw
Answer:
When an unbalanced force acts on the object, the object will accelerate in the direction of that force. ... An object in motion will stay in motion unless acted on by an outside force. An object at rest will stay at rest unless acted on by an outside force.
