  3. Verify conservation of energy principle

Concept of work as a measure of Energy


Work and energy are common concepts we always encounter in our lives on a daily basis. If one does not have energy, one cannot do any work. The stored up energy (potential energy) in our muscular system is converted to kinetic energy. When work and energy are related, they have the same unit of measurement called Joule.


Work is said to be done when a body moves in the direction of the force.... View More
