All of the energy an object has due to its MOTION and POSITION is called:
Mechanical Energy
100
How many types of Thermal Energy are there?
Three
Conduction, Convection and Radiation
100
Rubber, fabric, wood, and plastic are all examples of: Conductors or Insulators?
Insulators
200
The energy an object has due to its MOTION is called:
Kinetic Energy
200
True or False: Gravity is a constant FORCE
True!
Gravity is an invisible force that pulls objects toward one another.
200
Energy cannot be __________ or __________. It simply changes forms.
Energy cannot be CREATED or DESTROYED.
200
Which type of heat transfer is made through DIRECT CONTACT between two objects?
Conduction
200
Any material that PREVENTS (or slows down) the flow of heat or electricity.
Insulators
300
The ability to do WORK and cause changes in MATTER is called:
Energy
300
STORED energy an object has due to its current POSITION (where it is) or its current STATE (its properties) is called:
Potential Energy
300
At which position would the coaster have the MOST potential energy?
Position #5
This point is the highest off of the ground
300
Which type of heat transfer is through invisible WAVES that travel through matter and space?
Radiation
300
Any material that ALLOWS (or speeds up) the flow of heat or electricity.
Conductors
400
Analyze the data. Which object has MORE kinetic energy?
Object B, because it has a greater mass
400
Analyze the data. Which object has MORE potential energy?
Object B, because it is higher from the ground
400
At which position would the coaster have the MOST kinetic energy?
Position #3
The coaster would have the most motion at this position
400
Which type of heat transfer is made through the movement of FLUIDS (liquids and gasses)?
Convection
400
Provide an example of when you would want to use INSULATORS.
To keep heat in or out, to prevent burning, etc.
500
Analyze the data. Which object has LESS kinetic energy?
Object A, because it is moving slower
500
Analyze the data. Which object has LESS potential energy?
Object A, because it has a lighter mass
500
Provide an example of an object that has mechanical energy. When does it have potential energy? When does it convert into kinetic energy?
500
Label where you would feel CONDUCTION, CONVECTION, and RADIATION when feeling the heat from a fire
500
Provide an example of when you would want to use CONDUCTORS.
Cooking, heaters in homes, to heat up any object, etc.
