Types of Energy
A variable that never changes in an experiment and remains constant.
Control Variable
If an object moving at a given speed decreases its kinetic energy will ______________________.
What is decrease
Wind turbines convert _________________ energy into electrical energy.
What is kinetic
What type of resource can be replenished continually. Used over and over again. Example: solar and wind energy.
What is renewable resource
The type of Energy that depends on mass and position. Example: Cart on top of a roller coaster.
What is potential energy
When multiple sets of measurements are made during one scientific experiment. When you do something over and over again.
Repetition
As the speed of a falling object increases, its potential energy will _____________________.
What is decrease
Hydroelectricity can generate electricity because of the initial _______________________ energy of the water.
What is potential
What resource is used up faster that can't be replaced. Example: fossil fuels.
What is a nonrenewable resource
Type of energy that depends on the speed of molecules. Example: The type of energy that is produced from friction.
What is thermal or heat energy
Identify the independent variable: Does the amount of ice in a drink make the temperature of the drink colder faster?
Ice
When you drop a book on the floor, what happens to its potential energy?
What is the potential energy was transfered to kinetic, sound, and thermal energy
Wind energy, coal energy, nuclear energy, hydroelectric energy and solar energy all are used to make electricity. What tool is used to make electricity for these energy sources.
What is Turn a turbine that turns a generator to make electricity.
The large structure that helps turn hydroelectric energy to electrical energy. Example: They showed us two examples of these structures in the video yesterday.
Dam
Type of energy that depends on the flow of electrons
What is electrical energy
In a scientific experiment the variable that changes as a result of manipulation of the independent variables.
Dependent Variable
A basketball is dropped from a height of 2m and another identical basketball is dropped from a height of 4m. Which ball has more kinetic energy just before it hits the ground?
What is The basketball dropped from a height of 4m because it has more speed.
Hydroelectric energy uses ______________ energy of moving water and turns it into _______________ energy
Hydroelectric energy is using the kinetic energy of water and turning it into electrical energy.
Type of energy stored in chemical bonds
What is Chemical energy
Law or Theory: This scientific statement tells you "WHY" something is happening.
Scientific Theory
When you drop a tennis ball, it hits the floor and bounces back up. But, it does not reach the same height as before and each time bounce is smaller than the previous one. However, you notice the tennis ball is slightly warmer after it finishes bouncing. What type of energy is shown with the ball being warmer?
Thermal or Heat Energy
What type of energy is produced by splitting molecules to produce heat, boil water, create steam and turn a turbine? It also produces nuclear waste.
Nuclear Energy
Name 3 types of energy
Kinetic, Potential, Light, Heat, Chemical, Nuclear, and electrical
