Work and Energy MCQS for NTS Tests
WORK is accomplished when a Force Moves an object through a distance. Energy is added to a system when an external force moves a body. We can say that work is one form of energy. When a force acts from within a system, energy is removed from the system.
One example is stretching a Rubber Band. When you supply the force to stretch the rubber band, work/energy is added, but when you let go, the internal force of the rubber band contracts and moves the mass, so work/energy is removed from the system.
Another example is the gravitational force. If you lift a mass upward against gravity, work/energy is added and when the mass is dropped, work/energy is removed from the mass-earth system.
