♤If number of forces acting on a body make no difference in the position of the body then the force acted is called balanced force. ♤If a number of forces acting on the body push Or pull the body/make the body change its position then the force acted is called unbalanced force.

2Thank You

Nikita Nikita 3 years, 7 months ago

Balanced forces Unbalanced forces If a set of forces acting on a body produce no acceleration in it, then forces are said to be balanced. If a set of forces acting on a body produces some non zero acceleration, forces are said to be unbalanced. e.g. When we try to push a heavy box and it does not move, the force applied by us is balanced by the friction force acting on the box by the ground.e.g. When we drag a box on the floor, there is an unbalanced force acting on the box.
