What tool would you use to measure the average kinetic energy of particles in a sample of matter?
Thermometer
100
Which is an example of kinetic energy? A) a person standing on a diving board B) a desk C) a rock tumbling down a hill D) a bowstring pulled back
C) a rock tumbling down a hill The rock is moving.
100
A push or pull that acts on an object.
force
200
A change in speed.
acceleration
200
TOTAL kinetic energy of the particles in an object.
Thermal Energy
200
When using a thermometer, what are the two scales we can use measure temperature?
Celcius & Fahrenheit
200
How does the sun transfer thermal energy to the earth? (Name the method)
Radiation
200
Tendency of an object to remain at rest or to remain in motion.
Inertia
300
When you push a table across the floor, what opposing force is acting upon the table?
friction
300
AVERAGE kinetic energy of the particles of a substance.
Temperature
300
Builders put this inside walls and roofs of homes because it transfers thermal energy poorly.
Insulation
300
Air is an excellent __________. And why?
Air is an excellent insulator because the particles in air are spread apart so it takes longer for the energy to transfer.
300
Change in an object's position.
motion
400
This is done when a force moves an object over a distance.
Work
400
Transfer of thermal energy through the movement of a liquid or a gas.
Convection
400
Is the liquid inside a thermometer a conductor or an insulator? Why?
The liquid inside a thermometer is a conductor because it easily allows energy to transfer through it. That's why it moves quickly and is a good tool!
400
Which has more thermal energy? A) a bowl of ice cream B) a bowl of hot oatmeal (Same sized bowl and same amount of each)
B) a bowl of hot oatmeal
400
This is measured by dividing the distance an object moves by the amount of time it took to travel that distance.
speed
500
A measure of an objects speed AND direction.
Velocity
500
Transfer of thermal energy from one particle to another. (hint: through touching)
Conduction
500
What are some ways to increase the temperature in an object?
Accept reasonable answers
500
The inside of a fish tank gets heated by which form of energy transfer?
Convection
500
______________ energy is the sum of the potential and kinetic energy in an object.
Mechanical energy is the sum of the potential and kinetic energy in an object.
