Energy

Energy

is the ability to do work or cause change.

EVERYTHING has energy, but different kinds.

All energy can be split into TWO categories:

Kinetic (movement) and potential (stored).

Multiple Select

Select everything that has energy:

• Pencil

• Dog

• You (Human)

• Tree

• Plastic Cup

Multiple Choice

Potential Energy

• Movement

• Stored

Multiple Choice

Kinetic Energy

• Movement

• Stored

Subtypes of kinetic (movement) energy:

• Mechanical

• Radiant (light)

• Thermal

• Sound

• Electrical

Mechanical

• movement/ motion of objects.

• Mechanical or motion energy is actually the sum of kinetic and potential energy in an object that is used to do work.

Multiple Choice

Which has mechanical energy?

• A car speeding down the highway.

• A cup sitting on a desk.

Radiant/Light Energy

any electromagnetic (EM) radiation. Radiant/Light energy travels in the form of waves. Light energy travels in the form of waves. Light energy is very fast – in fact, nothing travels faster.

Radio Waves

Microwaves

Infrared

VISIBLE LIGHT

Ultraviolet

X-Rays

Gamma Rays

Multiple Choice

Which is a type of radiant energy?

• Microwaves

• Ocean waves

Thermal

• Heat energy from the vibration/ movement of a substance's molecules.

• The faster they move, the more energy the possess and the hotter they become.

• Type of kinetic energy

Multiple Select

Select all the items that have thermal energy:

• Ice

• Cup of coffee

• Pen

• Penny at -273 °C or 0 K (molecules so cold they are not moving)

Sound

• movement of sound waves.

• Sound energy is produced when a force causes an object or substance to vibrate.

• The energy is then transferred through the substance in waves called sound waves.
  

Multiple Choice

Sound waves can travel in space.

• True

• False

Electrical

• movement of electrons.

• Electrical energy is a type of kinetic energy caused by moving electric charges(kinetic energy).

• Lightning, batteries and even electric eels are example of electrical energy.
  
  

Multiple Choice

What is moving in electrical energy?

• Protons

• Neutrons

• Electrons

Subtypes of potential (stored) energy:

• Gravitational Potential Energy (GPE)

• Chemical

• Nuclear

Gravitational Potential Energy (GPE)

energy of position or place, has the "potential" to move.

Multiple Choice

What has gravitational potential energy?

• A book sitting on a desk

• A book sitting on the floor

Chemical

energy stored in the bonds between atoms and molecules.

EX: FOOD, batteries, coal, gasoline

Multiple Select

Which of the following has chemical energy? (select all that apply)

• Humans

• Fruits

• Coal

• Cows

• Batteries

Nuclear

energy stored in the *NUCLEUS* of an atom.

NUCLEAR power plants, stars or atomic bombs ONLY!!!

Multiple Choice

What has nuclear energy?

• Nuclear Power plant

• Stars

• Fireworks
