Terms
What is Energy
The ability to do work
What is Chemical Energy
Energy that is stored in Chemical bonds.
This Energy is used in waves. (two)
Radiant Energy/Light Energy
Energy can neither be
Created nor destroyed, but can only transform their forms of energy.
Is Hydro Electricity a fossil fuel?
No, Fossil Fuels are Coal, Oil, natural Gas
What is Kinetic Energy
What is an inexhaustible Resource
A resource that can not be used up by Humans
This Energy is the Energy that is associated with heat. What is this energy and how do we feel it if we are farther away from that source of heat?
Thermal Energy
Radiant Energy
Describe the energy transformation when tossing a baseball.
Potential- Holding it
Kinetic- Throwing up
Potential- Very top of toss before ball comes down
Kinetic- Ball coming down
Potential- holding the ball when it came down
What is a nonrenewable resource?
What is a renewable resource?
Example of both.
Non- A resource used up faster then it can be replenished. (Coal, Oil, Natural Gas)
Renewable- A resource that can be replenished continuously (Hydroelectricity)
Energy stored in the nucleus of an atom
Nuclear Energy
What are the 3 nonrenewable resources that we talked about?
Coal, Oil, Natural Gas
What is Temperature?
IF the particles inside an object are moving fast, what does that do to the temperature?
IF the temperature is low in an object, What dose that say about the object's particles speed?
Measure of average Kinetic Energy of the particles in a material.
Raise the temperature
Particles are moving slower.
_______________ causes mechanical energy to transform into ___________
Friction, Thermal Energy
If the outside Temp is 100 degrees and your indoor temp is 75 degrees; then in the winter your indoor temp is 75 degrees and the outside temp is 30 degrees, how does the heat pump work to warm and cool your building.
The water that is pumped into the house from the ground is the same temperature. Therefore, if the outside it hotter then the temp of the water, the water is cooling the house. but if the outside temp is colder then the water, then the water is warming the house.
What is also referred as light energy?
Radiant Energy
A device that transforms Kinetic Energy into Electrical Energy
Generator
What is Chemical Energy similar to? Why are they different?
Chemical Energy is energy stored in Chemical Bonds which is similar to Potential Energy. They differ based on Chemical Energy is stored in the Chemical bonds while Potential Energy refers to the Potential Energy of the whole object.
Describe the energy Transformation of a power plant using fossil fuels for generating electricity.
Chemical - form Fossil fuels
Thermal- Burning Fossil fuels heating water
Kinetic- water particles transforming to steam
Kinetic- Steam moving the turbine
Electrical- Turbine moving shaft in the generator transforming it into Electrical Energy.
Give the example of inexhaustible resource?
Solar Energy
What is the law of conservation of energy?
energy cannot be created nor destroyed, but can only change from form to form.
IF two non moving objects have the same mass, but one is higher and one is lower. The object that is in the higher position will have more what?
Potential Energy
IF Golf ball and Bowling Ball have SAME KINETIC ENERGY, which moves faster. Why?
IF both have SAME SPEED, which has more KINETIC ENERGY? Why?
Golf Ball- less Mass
Bowling Ball- More Mass
Does you body loose or gain Thermal Energy if you walk outside into 101 Degree weather? Where does Thermal energy travel?
Gain Thermal Energy
From Warmer material to colder.
Give the Energy transformations of a hydro electric dam.
Potential- Water behind the dam
Kinetic- Water moving down the shaft under the dam
Kinetic- Water moving the turbine
Electrical- Turbine moving a shaft in the generator transforming it into electrical energy.
