Which one of the following is a Renewable Resource?

• Coal

• Wind

• Crude Oil

• Fossil Fuels

Which of the following is a Nonrenewable Resource?

• Fossil Fuels

• Wind

• Nuclear

• Biofuel

What is energy measured in?

• Grams (g)

• Millimeters (mm)

• Joules (J)

What is potential energy? Example: Stretching a rubber band

• The energy of the object due to motion

• stored energy due to its position

What is kinetic energy? Example: Running

• The energy of the object due to the object's motion

• Stored energy due to position

What is electromagnetic energy? Example: x-rays & microwaves

• Kinetic energy of particles in an object.

• Charged particles, negatively charged particles move, creating a current.

• Forms of waves transmitted either through a medium or space

• Energy stored and then released when bonds break between atoms.

 What is electrical energy? Example: Light bulb

• The energy of electric charges

• Energy stored then released when bonds break between atoms.

• Kinetic energy of particles in an object.

• Stored in the nucleus. Breaks apart or two nuclei join together. 2 hydrogen atoms collide to create 1 helium atom.

What is chemical energy? Example: food, batteries & matches.

• Potential energy stored in chemical bonds

• Kinetic energy of particles in an object.

• Stored in nucleus breaks apart or 2 nuclei join together. 2 hydrogen atoms collide to create one helium atom.

• Energy changes from one form to another.

What is thermal energy? Example: hot light bulb

• Energy changes from one form to another.

• The total kinetic and potential energy of the particles of an object.

• Energy is conserved; can't be created or destroyed, it only changes form.

• Stored in nucleus breaks apart or two nuclei join together. 2 hydrogen atoms collide to create 1 helium atom.

What is energy transformation?

• Kinetic energy of particles in an object.

• Stored in nucleus breaks apart or 2 nuclei join together. 2 hydrogen atoms collide to create 1 helium atoms.

• Energy changes from one form to another.

• The ability to cause change.
