If you place a ball on a flat surface, it will remain there until unless you disturb it. It will move only when either you push it or pull it. This push or pull acting on an object is known as a force.
The force applied on an object can:
make the object move from rest.
change the speed of a moving object.
change the direction of motion of the object.
change the shape of the object.
Balanced forces do not change the state of rest or motion of the object on which they are applied. Unbalanced forces acting on an object may change its state of rest or motion.
1. What are balanced forces?
When two or more forces acting on an object in opposite direction balances each other then the forces are known as balanced forces.
2. Can a balanced force produces any acceleration in a body?
No. Balanced forces do not change the state of motion of an object.
3. What type of change can be produced by an unbalanced force in a body?
Unbalanced forces acting on an object may change its state of rest or motion.
