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 our solar oven).
What is light energy?
These charges attract or come together.
What are positive and negative or opposite charges?
The energy transformation that takes place when driving a car.
What is chemical to mechanical?
Why do two socks sometimes stick together in a dryer?
Electrons move from one sock to the other or static electricity.
The form of energy that is measured using a thermometer.
What is thermal energy?
True or false. An object moving with more speed has more kinetic energy.
What is true?
These charges repel or go away from each other.
The energy transformation that happens with a plugged-in lamp.
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?
True or false. Energy can be transferred from objects that touch as well as through empty space.
What is true?
Negatively charged objects have more of this particle.
What are electrons?
The energy transformation that happens in a hair dryer.
Which type of energy does a book have when it is sitting on top of a bookshelf?
What is potential energy?
The forms of energy that are types of kinetic energy.
What are thermal, light, and sound?
2 types of energy transfer that can cause motion or a change in position.
What is a push or pull?
Positively charged objects have more of these particles.
What are protons?
The energy transformation that happens with a plugged-in speaker.
What is electrical to sound?
Natasha set up two identical solar cookers. After 25 minutes solar cooker A is 85 degrees. Solar cooker B is 125 degrees. Which solar cooker is in the sun?
What is solar cooker B?
What are chemical, electrical, mechanical, thermal, light and sound?
The two things you need to measure to find speed.
What are distance and time?
This is how a switch works.
When the switch is on it closes the circuit or loop so electricity can flow. When a switch is off it opens the circuit or loop so the electricity cannot flow.
The energy transformation that occurs in a battery operated clock.
What is chemical to mechanical energy?
Aisha wanted to know how positive and negative charges affect balloons. The balloons are pushing away from each other. What are the charges on the balloons?
They are both positive or both negative.
