The force acting on a plastic bucket are:
• Gravitational force: It is acting downwards.
• Muscular force: It is applied by our hands to lift the bucket in upward direction.
Although these forces are acting on the bucket but no change is found in its state of motion because the two forces are balancing each other and as a result net force is zero.
