Two football linemen push against each other in practice. They do not move, but then lineman B moves forward and lineman A moves backward due to - The forces are balanced, but then line B exerts a greater force, causing unbalanced forces.
Balanced forces are forces that are applied to ao an object which is equal in size and opposite in direction. When these forces are balanced, there is no change in motion.
- In the given case, initially, forces applied by both linemen A and B are equal in size and opposite in direction, therefore, they do not move.
Unbalanced forces mean that the force applied on the object in one direction is greater than the force applied in the opposite direction.
- When unbalanced forces are acting on an object, there is a change in speed and/or direction.
- If an object starts to move, it must be because unbalanced forces are acting on it or greater force is exerted from the opposite direction of the object move towards.
- Later, linemen B move forward and linemen A move backward which mean there is the force applied by Linemen B is greater than the force applied Linemenen A.
Thus, in this case, it is happen due to - The forces are balanced, but then line B exerts a greater force, causing unbalanced forces.
