Energy Transformations
This is the process in which energy changes from one form to another.
What is an energy transformation?
This type of energy can be otherwise known as heat.
What is thermal energy?
In nuclear power plants, this type of potential energy is stored in the nuclei of cells until released.
What is nuclear potential energy?
True or false: a person person who is typing is doing work to the keyboard.
What is true?
Distance x force is the formula for this measurement.
What is work?
This law states that energy can not be created or destroyed; it can only be altered.
What is the law of conservation of energy?
This energy is sent through the Earth, causing platonic shifts and earthquakes.
The food you eat has this type of stored energy until you bite into it.
What is chemical potential energy?
A person is sitting in a chair. True or false: the chair is doing work to the person.
What is false?
A soccer player kicks a soccer ball 100 m with a force of 50 N. They have done this much work to the ball.
What is 5000 J?
In this process, the nuclei of cells are fused together.
What is nuclear fusion?
A ball that's thrown into the air has this type of stored energy mid-flight.
What is gravitational potential energy?
It's not magic! Roller coaster cars have this type of potential energy that's transformed into kinetic energy when they move downwards.
What is gravitational potential energy?
These two things must happen in order for work to be done.
What are a force acting on an object and that object moving at least somewhat in that direction?
A box is pushed 3 m with 10 N of force. This much work has been done to it.
What is 30 J?
This energy transformation occurs when a stove is turned on.
What is electric energy to thermal energy?
This type of energy is carried in electromagnetic waves.
What is radiant energy?
Gravitational potential energy depends on these two factors.
What are the objects mass and height above the Earth's surface?
Someone is walking with a backpack on and they stop and put the backpack down. True or false: they have done work to the backpack.
What is true?
A 6 kg ball is rolling at a speed of 2 m/s. It has this much kinetic energy.
What is 12 J?
In the process of photosynthesis, plants turn solar energy into this type.
What is chemical energy?
This type of energy comes directly from the sun and is used to provide both electric energy for us and chemical energy for plants.
What is solar energy?
Fossil fuels have this potential energy in them until it is extracted.
What is chemical potential energy?
A person turns on a conveyor belt and it begins to move. True or false: the person is doing work to the conveyor belt.
What is false?
You might need a calculator for this one. An object has a mass of 3 kg and sits on a table 3 feet above the ground. It has this much gravitational potential energy.
What is 88 J?
