Chapter 15Section 1.5

Mechanical Energy Mechanical energy is energy associated

with the POSTION and MOTION. Mechanical energy is a COMBINATION of

the objects potential and kinetic energy.

Mechanical energy = potential energy + kinetic energy

Nuclear Energy Nuclear energy is potential energy stored in the

nucleus of an atom and is released in a nuclear reaction. Nuclear fission – when a nucleus splits

used by nuclear power plants to produce electricity. Nuclear fusion – when nuclei of atoms fuse or join

together. Occur continuously in the sun, releasing tremendous

amounts of energy.
