What is kinetic energy?
Kinetic energy is energy an object has due to its motion. If an object isn't moving it doesn't have kinetic energy.
-
Kinetic energy and speed:
The faster something goes, the more kinetic energy the object has.
-
Kinetic energy and mass:
Kinetic energy increases as the mass of something increases.
-
What is potential energy?
Potential energy is energy stored in a object in a object because of its position. The higher the object is the more potential energy it has.
-
What is chemical energy?
Chemical energy is energy stored in an object and released when, for example, wood burns or another type of chemical reaction occurs.
-
What is thermal energy?
thermal energy increases as the temperature increases. For example, a cup of hot chocolate has more thermal energy than a cup of water
-
What kind of energy does your body produce and how?
Your body continuously produces thermal energy because of chemical reactions in your cells.
-
What is one way thermal energy is released?
Thermal energy is released by chemical reaction, which comes from chemical energy. (Eleanor, check to make sure this one is right.)
-
What is one way that energy is stored.
Energy stored in chemical bonds often contains chemical bonds with sugar.
-
What are chemicals made of?
Chemicals are made of atoms.
-
What happens to an object that has absorbed light energy?
An object that has absorbed light energy transforms into thermal energy.
-
What is a household example of electrical energy?
Electric stoves have coils that heat up when you turn them up. They begin to grow red from electrical energy.
-
What happens when chemicals are broken apart?
Chemicals are broken apart and new bonds are made which releases more energy.
-
Electrical energy carries. . .
Electrical energy carries negative and positive charges.
-
What is lightning?
Lightning is most commonly seen in the form of electricty. Lightning comes from an unequal distribution of electricity.
-
What are three forms of lightning?
Cloud to cloud, surface to cloud, and cloud to surface.
-
What kind of currents to batteries and outlets have?
Batteries are direct currents (DC) because of the positive to negative; and outlets are alternating currents (AC)
-
How is nuclear energy formed?
Nuclear energy is formed when the nuclei is split or fused.
-
What happens when the nucleus is split?
Huge amounts of energy are released when the nucleus (proton and neutron) is split.
-
How is energy released from the sun?
Much of the energy given off by the sun are fusion reactions.
-
What is light energy?
Light energy--bright or dull--electromagnetic energy that one can see.
