Forms of Energy and energy transformations lesson Monday 11/3

Forms of Energy & Energy Transformations

READ THIS BEFORE YOU START!
First, complete Quizziz assignment. There is a total of 80 slides but a lot of them are definitions, review information or instructions . Make sure to answer all questions.
You may work on Vocabulary as you are going over the quizziz lesson. Many definitions for the worksheet are found in here. This quizziz will help you to do the drawings, definitions and answer some of the questions.

Multiple Select

I understand I need to work on all questions and submit quizziz lesson by today while I also complete the vocabulary frayer model worksheet using definitions and drawings provided here to help me complete it on time and answer questions from worksheet as well.

• YES

• NO

• I didn't read the instructions but now I KNOW what I need to do during today's class

What is energy?​

​Energy - The ability to do work, or cause change

All energy is either a type of potential energy or a type of kinetic energy.

Potential energy is energy that is stored in objects.

Types of potential energy include: chemical energy, gravitational energy, and elastic energy.

Multiple Select

Select all the examples of potential energy.

• Gravitational energy

• Chemical energy

• Elastic energy

• Sound energy

• Thermal energy

Gravitational energy is energy that is stored in objects because of gravity.

The higher something is off the ground, the more gravitational potential energy it has.

Elastic energy is energy that is stored in objects that are compressed or stretched.

​Chemical Potential Energy

• ​Bonds between atoms could POTENTIALLY be broken or formed.

• ​What does this cause?

• This grilled cheese sandwich has the POTENTIAL to be eaten and broken down for energy inside your body. Unfortunately it will remain chemical potential energy because you can't eat it ;p

Chemical energy is energy that is stored in the chemical bonds of objects atoms.

Kinetic energy is energy due to motion. Anything that is moving has kinetic energy.

Types of kinetic energy include: thermal energy, electrical energy, radiant energy, and sound energy.

Multiple Select

Select all the examples of kinetic energy.

• Chemical energy

• Elastic energy

• Thermal energy

• Sound energy

• Radiant energy

Mechanical Energy is the energy of moving things.

• A stack of firewood

• An apple

• A person yelling

Multiple Choice

Which object below has mechanical energy?

• The blades on a fan turning

• A tank of gasoline

• An electrical outlet

• A fire burning

Thermal Energy is the total amount of atom movement in an object.

Thermal Energy is the total amount of atom movement in an object. We see this as how much heat an object has.

Multiple Choice

Which object below has thermal energy?

• The blades on a fan turning

• The muscles in your body

• An electrical outlet

• Firewood burning

Multiple Choice

• A plant

• A pile of firewood

• A candle

Multiple Choice

Which object below has sound energy?

• A radio

• A solar panel

• A tank of gas

• A battery

Radiant energy is energy that is moved by electromagnetic waves.

Multiple Choice

Which object below has or uses light energy?

• A radio

• A solar panel

• A tank of gas

• A battery

Energy Transformations

The law of conservation of energy states that energy cannot be created or destroyed, it just changes forms.

An energy transformation occurs when energy is changed from one form to another.

An Electric Pencil Sharpener

An electric pencil sharpener starts with ELECTRICAL energy because it won't work if you don't plug it in. It ends with MECHANICAL energy because you want the blades to move to sharpen your pencil.

The battery has chemical energy and the flashlight uses that energy to make light.

A Person Running

A person running starts with CHEMICAL energy because you can't run if you don't have energy stored in your muscles. It ends with MECHANICAL energy because you are moving.

A Wind Turbine

A wind turbine starts with MECHANICAL energy because the wind moves the blades. It ends with ELECTRICAL energy because the moving blades generate electricity.

Now it's your turn
