Energy Study Guide

Define nonrenewable resource.

• Energy that can not be remade quickly or reused. Once it is used up, it is gone.
• Energy that can be remade quickly and reused. It is never gone.

What are the two types (categories) of Energy?

• Kinetic & Potential
• Potential & Electrical

Define potential energy.

• Energy of position / stored energy.
• Energy of motion.

Define kinetic energy.

• Energy of motion.
• Energy of position / stored energy.

When does an object have more potential energy?

• The higher it is from the ground.
• The closer it is to the ground.

When does an object have more kinetic energy?

• When it hits the ground/reaches bottom point OR when it has more mass.
• When it hits the sky/reaches top point OR when it has less mass.

Think of the Energy Skate Park. When did the skater have the greatest potential energy? Explain.

• The skater had the greatest potential energy when he was at the top of the track because he is the highest point it will go. 
• The skater had the greatest potential energy when he skater was at the bottom of the track because it is the lowest point he will go.

What kind of energy is created when 2 objects interact with each other?

• thermal
• kinetic

What energy type/category do fossil fuels (coal, oil, and natural gas) have before they are burned?

• Thermal
• Potential

What is the "law of conservation of energy"?

• Energy can not be created or destroyed - only transformed from one form to another.
• Energy can be created or destroyed  and be transformed from one form to another.
