What is the definition of energy??
What is Kinetic Energy?
Kinetic Energy is the energy of an object in motion!
You hear someone singing. What type of energy is this?
Singing is a type of Sound Energy
A bouncy ball is rolling down the hallway. Is this kinetic or potential energy?
This is Kinetic because it is moving!
When you run laps, what energy is being expelled?
HEAT
What is Friction?
A force that resists the motion of two objects
What is radiation?
The type of heat transfer that comes in waves like the Sun
You're outside running your laps. What kind of energy is running?
Running would be an example of Mechanical Energy! This is the energy of movement.
Mrs. V’s starbucks is on her lab table. Is this kinetic or potential energy?
Just the cup is Potential because the physical cup isn't moving.
What happens when molecules heat up?
What is Potential Energy?
Potential Energy is the amount of stored energy an object has
What is Convection
That heat transfer that is like a circle. Heat rises while cool sinks. This creates wind!
Your mom starts the car by turning the key. What type of energy starts the car?
The custodian is climbing the ladder to get on the roof. Is this kinetic or potential energy?
The custodian moving up the ladder is Kinetic Energy! Moving = Kinetic
What are we measuring when we take the temperature of something?
When we measure the temperature, we're measuring the Kinetic Energy an object has.
What is conduction?
Conduction is the heat transfer when two objects touch!
What does the Law of Conservation of Energy state?
That energy cannot be created or destroyed!
After it rains you see a rainbow! What kind of energy is this?
Seeing a rainbow would be Electromagnetic Energy! The energy of waves.
Mrs. V pulls on her hair tie and then stops. Is this kinetic or potential energy?
The stopped hair tie is Potential Energy. It has a lot stored because Kinetic Energy was used to pull it.
What has move Heat Energy, a cup of boiling water or a bucket of warm water?
The bucket has more Heat Energy because it has more molecules!
More molecules = More HEAT
What is another name for heat energy?
Heat Energy is also called thermal energy!
What is an insulator?
An insulator is anything that holds heat in easily!
Mrs. V rubs her hands together. What energy is being produced because of the Friction?
Heat Energy! Any time you move, some heat energy is happening too!
When Mrs. V put the beaker on the hot plate that was both an example of conduction and convection. Why?
It is Conduction because the beaker is TOUCHING the hot plate. It is ALSO Convection because the hot water goes UP and the cold water SINKS.
What is the Latin word for HEAT?
