Question

Describe an activity to demonstrate balanced force

Answer 1

Consider another example involving balanced forces - a person standing on the floor. There are two forces acting upon the person. The force of gravity exerts a downward force. The floor exerts an upward force.

Since these two forces are of equal magnitude and in opposite directions, they balance each other. The person is at equilibrium. There is no unbalanced force acting upon the person and thus the person maintains its state of motion.

Answer 2

Answer:

Consider some children pushing a heavy box on a  rough surface with some force.

• The box does not move due to the friction  between the surface and the box, which  balances the applied force.
• The applied force is still increased but the  friction again balances with the applied  force
• When the box is pushed with still a greater  force, the applied force becomes greater than  the frictional force. The force acting on the box  is unbalanced and the box moves.
