Forms of Energy
What form of energy is associated with flowing electrons?
Electrical Energy
What term means to completely change from one form of energy to another?
Transform
What is the Law of Conservation of Energy?
Energy cannot be created or destroyed but can be transformed.
What is the definition of energy?
Energy is the ability to do work or cause change.
The Scientific Method begins with what?
The scientist asking a question
What form of energy is heat through contact?
Thermal Energy
What terms means moving something from one place to another?
Transfer
What is the difference between conservation of energy and energy conservation?
Conservation of energy is the law that we can not create or destroy energy but it can be transformed. Energy conservation is using our resources wisely (not wasting)
What is the definition of work?
A force acting on an object causing that object to move in the direction of that force
What is a hypothesis?
A prediction or educated guess
What form of energy travels in waves?
Radiant energy
What energy transformation occurs when you turn on the classroom lights?
Electrical energy transforms into radiant energy.
True or false: When someone turns on a light, radiant energy is created.
False. Electrical energy is being transformed to radiant energy. (energy cannot be created)
What are the four main forms of energy we have studied?
Thermal, Electrical, Radiant, Mechanical.
What is an independent variable?
A variable that I (the experimenter) purposefully change
What do we call the type of energy an object has due to a change in motion and position?
Mechanical energy
What energy transformation takes place when you turn on a microwave?
Electrical to mechanical, radiant, sound, and thermal.
Any example of energy transformation is an example of conservation of energy?
True
When a baseball player hits a ball with their bat, energy is being transferred from the ___ to the ____.
bat, ball
What is a dependent variable?
The factor that changes because of the independent variable
T.E.R.M.
Electrical energy is transformed into radiant (light) and thermal (heat)
True or False: If your TV remote has a dead battery, the electrical energy was destroyed?
False. (energy cannot be destroyed)
Ms. Deel, Mrs. Pace, Mr. Page, and Mr. Nash tried to push a boulder. None of them were able to move the giant rock at all. Was work done to the boulder?
No. For work to be done the object has to move in the direction of the force.
An investigation was done to determine if the amount of sugar given to a plant affected the amount of time it bloomed.
What is the independent and dependent variable?
Independent- The amount of sugar
Dependent- The time the plant bloomed
