The Nature of Energy Motion, Force & Energy Chapter 5.1 Pages 140-145
What is Energy? • Energy is the ability to do Work or cause a change • Measured in Joules, like Work
Kinetic Energy • Kinetic Energy is the energy of motion • All moving objects have Kinetic Energy (KE) • What determines an object’s KE? • Mass & Velocity determine the KE of an object.
Potential Energy • Potential Energy (PE) is stored energy • It has the potential or “possibility” to do work • Gravitational PE is energy that depends on height • Elastic PE is for objects that can be stretched.
Mechanical Energy • Energy associated with motion (KE & PE)
Thermal Energy • Energy of particles in an object
Chemical Energy • Energy stored in chemical bonds
Electrical Energy • Moving electric charges
Electromagnetic Energy • Waves of energy, such as light
Nuclear Energy • The fusion or fission of atoms
