Forms of Energy
The form of energy that is the total potential and kinetic energy and has to do with motion.
What is mechanical energy?
A type of energy that can travel through empty space but can also cause objects to warm up. (Think of a solar oven).
What is light energy?
The energy transformation that takes place when driving a car. (2)
What is chemical to mechanical?
During our Chemical Reaction experiment (baking soda, vinegar, yeast, hydrogen peroxide), What did we use to observe the materials before mixing them?
Our 5 senses: Sight, Hearing, Touch, Taste, Smell
The form of energy that is a change in temperature.
What is thermal energy? (heat energy)
A type of energy that cannot travel through empty space and uses waves.
What is sound energy?
The energy transformation that happens with a plugged-in lamp. (3)
What is electrical to light and thermal energy?
Describe a way that you could decrease the thermal energy of a cup of water?
Cool it by putting it in the freezer or refrigerator.
The form of energy caused by the movement of electrons.
What is electrical energy?
Mechanical energy is the cause of motion. What types of motion energies are there?
What is Kinetic energy and Potential energy?
The energy transformation that happens in a hair dryer. (3)
What is electrical to thermal and sound?
List at least 3 things that have potential energy.
1. Apple in a tree 2. Ball at the top of a hill 3. Rollercoaster at the top
Answers may vary.
The forms of energy that are types of kinetic energy due to their use of waves.
What are thermal, light, and sound?
Describe how an object with potential energy could change to having kinetic energy.
Apple on a tree has potential energy because it's just hanging there. It could have kinetic energy if wind makes it move back and forth or if the apple falls and rolls on the ground it is moving which is kinetic.
Answers may vary.
The energy transformation that happens with a plugged in pencil sharpener. (4)
What is electrical to mechanical, sound, and thermal?
You are outside for recess playing soccer. List all energies you are using to play. (5)
Chemical, Mechanical, Light, Heat, Sound
Chemical energy powers your body which allows you to use mechanical energy to move. The sun and moving then use thermal energy which makes you hot and sweaty. The sun uses light energy so you can see the ball. You use sound energy to communicate with teammates as you play.
What are chemical, electrical, mechanical, thermal, light and sound?
List an object for each that uses that energy:
Light Mechanical Sound
Heat Chemical Electrical
Light: Lamp Mechanical: People Sound: TV
Heat: Oven Electrical: Sharpener
Chemical: Battery powered clock
Answers may vary.
The energy transformation that occurs in a battery operated clock. (2)
What is chemical to mechanical energy?
List how each energy causes motion or a change:
Light Sound Electrical
Chemical Mechanical Heat
Light: Makes a dark room brighter Sound: Hitting a drum causes a loud boom Electrical: Used to power a sharpener Chemical: Batteries transfer to electrical energy which powers many things Mechanical: Helps your body move from one place to another Heat: An object can go from hot to cold or cold to hot
