Chemical energy is the energy stored in the bonds of atoms that make up substance.

Electrical energy is the movement of electrons. Lightning and static electricity are examples of electrical energy that occur naturally.

Nuclear energy is the energy stored in the nucleus of an atom. Nuclear energy is unusual in that it can give off energy in the form of light or heat, but it is the change in the atom's makeup that produces the energy. Submarines, power plants, and smoke detectors all use nuclear energy. Nuclear power plants use uranium, a radioactive element, to create electricity.

Thermal energy is the internal energy in substances-the vibration and movement of atoms and molecules within substance. Thermal energy is created in the movement of atoms. .

Sound energy is the movement of molecules in the air that produces vibrations.

Mechanical energy is the movement of machine parts. Mechanical energy is also the total amount of kinetic and potential energy in a system.

Transformation of energy

Transformation of energy • change from one form energy to another form of energy

Example : transformation from Potential to kinetic energy

Example: Name the forms of energy that transform

Example: Name the forms of energy that transform

Law of conservation of energy • When one formed of energy is transformed to another, no energy is destroyed. • Energy is always changing from one form into another form • The total energy of an object never changes

Let’s watch this!!!!!

Potential and Kinetic Energy Potential Energy Kinetic Energy • Energy at rest • Stored energy , has the potential to deliver work • Depends on mass and height of an object • Action energy • Energy in motion • Depends on mass and speed of an object

P. E. and K. E Different forms of Potential Energy • Gravitational potential energy – is the energy stored by objects lifted off the ground Elastic potential energy – stretched objects Nuclear energy –stored energy Chemical energy- stored energy Different forms of Kinetic Energy • Mechanical energy • Sound energy • Light energy (electromagnetic) • Thermal energy
