Introduction to Conservation of Mechanical Energy with Demonstrations

The video tutorial explores three types of energy: kinetic, gravitational potential, and elastic potential. Mr. Terry demonstrates an experiment by dropping a mass to illustrate energy concepts. The tutorial covers calculations of kinetic and gravitational potential energy, graphing energy changes, and the conservation of mechanical energy. It explains conditions under which mechanical energy is conserved, using examples like a pendulum to demonstrate energy transformation.

Under what conditions is mechanical energy conserved?

Provide an example of when mechanical energy is not conserved.

How does the pendulum demonstrate the conservation of mechanical energy?
