Question

Which of the following situation is not the effects of force?

• A. When you push a box kept on the table.
• B. When you push the wall of your classroom.
• C. When you pull the door to open.
• D. When you pull the end of a rope in the game of tug of war.

Answer 1

The correct option is B When you push the wall of your classroom.

When a force is applied on a stationary object it can make it move. For example, when you push a box kept on the table when you pull the door to open when you pull the end of a rope while playing tug of war. But it is not necessary that a force can always make a stationary object move. For example, if you try to push the wall of your classroom, it will not move. Even if all the students in your class push the wall, it will not move. It is just because the net force applied is not sufficient to move the wall.
