The energy that an object has due to the position, condition, or chemical composition.
What is Potential Energy?
100
The energy in an object due to its motion.
What is kinetic energy?
100
The transfer of one substance to another from direct contact.
What is conduction?
100
The transfer of heat through a liquid or gas.
What is convection?
100
Transfer of energy through electromagnetic waves.
What is Radiation?
200
Ex: When you are on top of a skate ramp.
What is an example of potential energy?
200
Ex: When you are skating down the ramp.
What is an example of kinetic energy?
200
Ex: When your hand is touching the boiling hot kettle.
What is an example of conduction?
200
Ex: When heat is reflected from the pool or the steam.
What is an example of convection?
200
Ex: The electromagnetic waves in the sun.
What is an example of radiation?
300
When there is kinetic energy.
When is the potential energy zero?
300
When there is potential energy.
When is kinetic energy zero?
300
Conduction is the process by which heat energy is transmitted through collisions between neighboring molecules.
What is conduction is the atmosphere?
300
When warm air rises, it creates an upward current in the atmosphere.
What is convection in weather forms?
300
Radiation is energy given off by matter in the form of rays or high-speed particles.
How is radiation made?
400
Potential energy is so important because it has gravitational potential energy because gravity is working to pull it down.
Why is potential energy so important?
400
Yes! This relationship is call word-energy theorem.
Is work done equal to kinetic energy?
400
Conduction work best in solids as their atoms/molecules are located closer together.
How does conduction work in a solid?
400
Convection cooking is used with a convection oven which circulates hot air with a fan.
What is meant by convection cooking?
400
Radiation comes from the exposure from cosmic rays and radioactive material in the earth.
Where does radiation come from?
500
We can use elastic potential energy by using the formula: PE = 1/2(kx^2).
How do we use elastic potential energy?
500
The formula for calculating kinetic energy (KE) is KE = 0.5 x mv2.
How do you calculate the change in kinetic energy?
500
First, heat is transferred from the molecules of the hot range surface to the molecules of the adjacent pan bottom, then from the pan bottom to the pan sides and the food contained within the pan.
What foods are cooked by conduction?
500
Convection currents work often when heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the aesthenosphere.
How does a convection current work?
500
They are give off in atoms such as neutrons and protons in the nucleus and electrons orbiting the nucleus.
