100
The ability to do work.
What is energy?
100

The energy stored in food, fossil fuels, and batteries.

What is chemical energy?

100

A bowling ball rolling down a lane is an example of...

What is kinetic energy?

100

The chemical energy stored in a battery is a type of this.

What is potential energy?

100

The average kinetic energy of particles in matter.

What is temperature?

200

The SI units used to measure the energy of matter.

What are Joules?

200
Energy an object has due to its motion, position or condition.
What is mechanical energy?
200

The mathematical formula for kinetic energy is...

What is KE = 1/2 m v2?

200

The mathematical formula for potential energy is...

What is PE = mgh or PE = wh?

200

Describe the difference between thermal energy and temperature.

Thermal energy is the total energy in a sample of matter, and therefore depends on mass.  Temperature is an average measure of the energy in matter.

300
The energy any object has because of its motion.
What is kinetic energy?
300

Energy formed when an atom splits apart or when two atoms join to form one.

What is nuclear energy?

300

If a ball is rolled to the top of a hill and brought to a stop, what can we say about its kinetic energy?

It is close to/equal to 0 J.

300

Where does a pendulum have the LEAST potential energy?

At the very bottom of it's swing.

300

Which has more thermal energy and why? A lit match, or a 200 kg ice sculpture?

What is the ice sculpture because it has more mass?

400
Stored energy or energy that an object has due to its position.
What is potential energy?
400
Energy stored in the way atoms are connected to each other.
What is chemical energy?
400

Find the kinetic energy of a 2 kg ball moving at 4 m/s.

What is 16 J.

400

If a kitty is suspended 20 meters above the Earth and has a weight of 5 kg, then what is its potential energy?

What is 100 J?

400

What are the SI units for temperature?

What are degrees Celsius or Kelvin?

500

Energy cannot be created nor destroyed, it can only change from one form to another.

What is the law of conservation of energy?

500
Energy of the movement of atoms and molecules.
What is thermal energy?
500

Find the mass of a ball that is moving at 2 m/s with 20 J of kinetic energy.

What is 10 kg?

500

Gravity on Earth causes an object to accelerate at about 10 m/s2.  If an object has 40 J of potential energy and has a mass of 2 kg, then how high is it off the ground?

What is 2 m?

500

Which of the following molecules would you predict to have more thermal energy and why? CO2, H2O, C6H12O6, or CH4?

What is C6H12O6 because it has more atoms and therefore more potential for movement?
