Energy is the ability to do what? What do we use to do work?

WORK, ENERGY

The unit of Energy is in

JOULES

1= BTU or (British thermal Unit) is equa to how much energy?

1 BTU= 1000 J

The conservation law of energy states that

energy can be transfered between different forms, not created or destroyed.

5 main forms of energy?

Mechanical, Heat, Chemical, Electromagnetic, Nuclear

Mechanical Energy is associated with what?

MOTION, if its moving, than it has mechanical energy.

Heat energy is caused by what?

The Internal motion of atoms

How does Heat energy increase..?

The faster the particles move, the greater amount of heat energy is given off.

How can mechnaical energy be converted into heat energy

Movement that causes internal particles to move, (rubbing your hands)

Chemical Energy

Eneergy related to the breaking and reforming of bonds from chemicals

Electromagnetic energy

Associated with moving charges..

Nuclear Energy

Assoicated with energy from the nucleus or atom

Describe specifically what happens in Nuclear Energy

When the nucleus splits or is joined together, energy is released in the form of light and heat energy (atomic)

Nuclear energy can be from what?

FUSSION or FISSON

FISSION does what?

Split the atom.

Fusion does what?

Combines two atoms.

What is Mechanical Energy

Energy due to an object’s positional (PE) or motion (kinetic)

Describe the chart that divides energy

Potential and Kinetic, Potential splits into three different subsections: Gravitational potential energy, Elastic Potential Energy, Chemical Potential Energy

What is Potential Energy?

Energy that is stored, waiting to be converted into
