Terms in this set (53)
The ability to cause changes in matter; that which living things use to live, grow, and move.
True or False: Energy can cause change in matter.
True or False: Energy can change from one form to another.
True or False: Energy can be all used up until there is none left.
Does a book on a shelf have energy?
Yes. Someone gave it energy by lifting the book to the shelf. The energy is now stored in the book.
Energy an object has because of its position or its condition
The energy an object has because of its motion.
When a roller coaster is at the top of a hill, most of its energy is potential energy due to its position. What will change this potential energy to kinetic energy as the roller coaster starts down the hill?
Gravity. The kinetic energy again becomes potential energy as the roller coaster starts up the next hill.
Sound energy is what three things
1. a form of energy that is carried as waves in vibrating matter.
2. a type of kinetic energy, because particles of matter are moving.
3. the cause of all the sounds you hear.
The total kinetic energy that makes up a substance.
What measure thermal energy?
What do you sense thermal energy as?
A form of energy that can travel through space. Light can also pass through some types of matter, such as air or glass. Light travels as waves.
Energy caused by the movement of electric charges.
Can electrical energy change to other types of energy?
The total energy of motion and position of an object.
What is the equation that shows the relationship between potential, kinetic, and mechanical energy?
Mechanical energy = kinetic energy + potential + energy
Energy that is stored in matter and that can be released by a chemical reaction.
Give examples of something that uses chemical energy.
Your body, cars, flashlights, stoves.
Winding the key on a toy increases the toys ___________ energy.
Our bodies use the ______________ energy in food to move and stay warm.
The hands on a watch move because the watch has __________ energy.
List three sources of light.
The sun, fires, lightning bugs.
Describe how energy in gasoline is transformed in a lawn mower.
Gasoline contains stored chemical energy. When gasoline is burned in a lawn mower, the energy is transformed into mechanical and thermal energy.
To move back and forth.
Form of energy you can hear?
Form of energy you can see?
What your body feels thermal energy as?
What causes hair to stand out when touching an electrically charged object?
Each strand of hair has become charged in the same way, so the strands repel one another.
A property of a particle that affects how it behaves around other particles
Protons have a _________ charge?
Electrons have a __________ charge?
Neutrons have a ________ charge?
________ sometimes gain or lose electrons.
Particles with same charge _________ one another.
Particles with opposite charges _________ one another.
When you touch something, the electrons Jump from your finger (negative charge) to the object (positive charge). This jumping is called _____________?
When the difference in charge between a cloud and the ground is great enough, there is a huge electrostatic discharge that we call __________.
List Three devices that use electric current from batteries.
Flashlight, cell phone, calculator
List three devices that use regular house electric current.
Stove, television, computers.
Electricity is produced at a generating ________, may use water, coal, or atoms (Nuclear) to produce the electricity you use.
Where are the particles found in an atom?
Protons - Nucleus
Neutrons - Nucleus
Electrons - Cloud
Now we turn on a switch and the light comes on in our homes. In colonial times, homes were lit with ________.
We use an electric stove to cook our dinners or a microwave to heat up food; in colonial times, people wood use a ________ to cook all their meals?
Moving a magnet and a wire near each other produces an __________.
Inside a ________, the mechanical energy of falling water is used to turn generators, which change mechanical energy into electrical energy.
It is important to ________, or use less electricity as some natural resources will run out and renewable energy sources are not yet efficient enough to be solely relied upon.
The buildup of electric charges on an object.
A device that converts electrical energy into mechanical energy.
A device in which current produces magnetism.
A device that converts kinetic energy to electrical energy.
What kind of energy are represented a picture with fireworks exploding?
Many kinds of energy including chemical, thermal, sound, light, energy of motion, and energy of position are represented.
Movement of electrons from one place to another.
