Energy Review

Types of Energy

There are TWO MAIN types/categories of energy.

Kinetic [MOVEMENT]

Potential [STORED]

Open Ended

Give ONE example of Kinetic Energy.

Open Ended

Give ONE example of Potential Energy.

Types of Kinetic Energy

• M --Mechanical [Moving parts]

• E --Electrical [Flow of electrons]

• L --Light [travels in waves]

• T --Thermal [heat energy]

• S --Sound [is heard]

Types of Potential Energy

• Gravitational [change in height]

• Elastic [Energy stored in elastic objects]

• Chemical [stored in the bonds of molecules]

• Nuclear [stored in the nuclei of atoms]

Multiple Choice

A basketball is being held in the hands of a player. This shows...

• Potential energy

• Kinetic energy

Multiple Choice

What kind of energy is in a waving hand?

• Potential
• Kinetic

Multiple Choice

What kind of energy is in a moving skateboard?

• Potential
• Kinetic

Multiple Choice

What kind of energy is in a rock at the edge of a cliff?

• Potential
• Kinetic

Multiple Choice

__________ is stored energy.

• Potential

• Kinetic

Multiple Choice

The faster an object moves, the ________ kinetic energy it has.

• more

• less

Energy Transformations

Energy is NOT created NOR destroyed; it just changes forms.

When you turn on your chromebook [not plugged into the outlet] chemical energy in the battery is then converted to electrical energy. That electrical energy is converted to light, sound, and thermal energy as you use your chromebook.

If you are standing by a campfire, the wood is chemical potential energy. As the bonds are broken down, thermal, light, and possibly some sound energy are transformed from the potential chemical energy.
