100

Potential energy is _ energy.

Stored

100

Kinetic energy is energy an object has due to its _. 

position

100

When you plug a tv in it transforms _ energy to _ energy.

Electrical; sound/light

100

What are the two types of energy?

Potential and kinetic

100

The formula for kinetic energy is KE= 1/2mv2. What do m and v stand for?

mass; velocity

200

This is energy due to position or place.

Gravitational energy

200

This is energy due to the movement of objects from one place to another.

Mechanical energy

200

When you plug in a toaster it turns _ energy into _ energy.

Electrical; thermal

200

Energy is the ability to do _. 

work

200

If the formula for kinetic energy is 1/2mv2, what is going to affect an objects kinetic energy more? M or v?

v (velocity)

300

This is energy stored in objects by tension.

Stored mechanical energy (elastic energy specifically)

300

This is a type of energy when atoms/molecules vibrate to cause heat.

Thermal energy

300

When you eat food and then go for a bike ride you are turning _ energy into _ energy.

Chemical; mechanical

300

Energy makes matter _ or _. 

Move; change

300

The formula for potential energy is P= mgh. What does the g stand for? Specifically what number with units?

gravity= 9.8 m/s2

400

This is energy stored in the bonds of molecules.

Chemical energy

400

This is the term for the type of energy when light travels in transverse waves.

Radiant (or electromagnetic) energy

400

When you plug in a generator because your power went out you are turning _ energy into _ energy.

mechanical; electrical

400

What are the units for energy?

Joules

400

If an object weighs 2kg and is at height of 10m, what is its potential energy? (don't forget units!)

P= mgh

P= (2kg)(9.8m/s2)(10m)

P= 196 joules

500

This is energy stored in the nucleus of an atom.

Nuclear energy

500

Name both of these types of energy: 

Energy from the flow of an electric charge (electrons moving in one direction)

Energy that travels in longitudinal waves

Electrical energy; sound energy

500

When you turn on a flashlight you are turning _ energy into _ energy.

Chemical; electrical/radiant

500

What is the name of the law that describes how energy cannot be created or destroyed?

The Law of Conservation of Energy

500

What is the Kinetic Energy of a 150 kg object that is moving with a speed of 15 m/s?

KE = ½ (150kg) (15 m/s)2

KE = ½ (150kg)(225)

KE = 16,875 J
