Week 5 – Lesson 2 (Mechanical Energy)
Date: November 2020
Topic: Mechanical Energy
Mechanical energy is a form of energy. It is all the energy that an object has because of its
motion and its position. All living things and all machines use mechanical energy to do work.
WHAT IS POTENTIAL AND KINECTIC ENERGY? Mechanical energy is the moving energy (kinetic energy) of an object plus that object's stored energy (potential energy). The mechanical energy of the pendulum toy shown here includes the kinetic energy of the balls in motion plus the potential energy of the balls that are still. The pendulum below demonstrates this concept. For a in-depth look into Kinetic energy and Potential energy watch the video below
