Forms of Energy Study Guide

What is energy?

• The amount of “stuff” in an object
• A way to describe the volume of an object
• The ability to do work
• A push or a pull

What is work?

• Changing the physical properties of an object
• Changing the chemical properties of an object
• Applying a force to move or change something
• Both a and b

What type of energy is associated with an object’s motion or position?

• Mechanical energy
• Light energy
• Electrical energy
• Thermal energy

What type of energy is carried by electromagnetic radiation, such as radio waves, UV light and x-rays?

• Sound energy
• Light energy
• Thermal energy
• Electrical energy

Sound energy is created when:

• An object moves across a long distance
• An object absorbs thermal energy
• An object vibrates
• An object falls to the ground

What type of energy is stored in food and fuel?

• Radiant energy
• Mechanical energy
• Thermal energy
• Chemical energy

What unit tells you how much energy is needed, stored or applied to perform work?

• Joule
• calorie
• Calorie
• All of the above

What is power?

• The total amount of energy in an object
• The time is takes to use up all an object’s energy
• The rate at which energy is used
• The rate at which a force moves an object across a distance

The movement of the SAME form of energy from one object to another is called:

• Energy transfer
• Energy transformation
• Work
• Power

The conversion of energy from one form to another is called:

• Energy transfer
• Energy transformation
• Work
• Power
