Define and give the unit for energy

A 100

Energy it the ability to do work or cause change, and is

measured in Joules (J)

A 100

A decrease in either of these factors will

decrease the kinetic energy of an object

A 200

Mass or velocity

A 200

What is the difference between Gravitational Potential Energy and

Elastic Potential Energy. How are they

similar?

A 300

Both Gravitational and Elastic PE are stored

energys, that is they are not currently being used. GPE is

stored in the height of an object above the ground,

and EPE is stored in a stretch or compression

A 300

At what point(s) in its swing does the above object have

its maximum potential energy? Explain. A 400

Maximum Potential energy is a point A,

because that is where the pendulum is

highest above the ground.

A 400

What energy conversions are taking place at point D, as the ball moves toward point

E?

A 500

The kinetic energy of the pendulum is being

converted into potential energy as the

pendulum gets higher.

A 500

Define chemical energy.

B 100

Chemical energy is energy stored in the nucleus of an

atom.

B 100

How are mechanical energy and kinetic

energy similar? How are they different?

B 200

Both mechanical energy and kinetic energy deal with the energy of moving object, but

mechanical energy also includes the potential energy

of objects due to their location.

B 200

A moving object usually converts mechanical energy

into what form of energy? What causes the conversion?

B 300

Moving objects usually convert mechanical energy into thermal

energy, as a result of friction.

B 300

Describe the main conversions which take

place when drops a basketball.

B 400

The gravitational potential energy the basketball gained when it was picked up is converted into kinetic

energy as it falls. When the ball hits the ground, that kinetic

energy is converted into elastic potential energy as the ball

squishes, and then converted back into kinetic and gravitational PE.

B 400

How are temperature and heat related?

B 500

Objects will transfer thermal energy as heat, until they

are the same temperature. Temperature differences

drive heat transfer.

B 500

Give three examples of chemical energy

C 100

Matches, gasoline, food, wood, candle

wax, leaves, etc

C 100

What forms of energy are present in the

picture above?

C 200

Chemical (the food), mechanical (the spinning

blade and the moving person), electrical (the cord),

sound (the noise), thermal (the blender motor gets hot)

C 200

What form(s) of energy could be found in the picture above?

C 300

Electromagnetic/light energy (from screen), electrical

energy (cord from TV and to gaming system), sound

energy (volume), mechanical energy (guy pushing buttons

on controller), thermal energy (TV gets hot)

C 300

DAILY DOUBLE

C 400

DAILY DOUBLEPlace A Wager

Give 5 forms of energy present in the diagram above.

C 400

Chemical (plants and fuel), Sound (noise of engine),

Mechanical (moving plane), Electrical (control panel),

Thermal (plane’s engine gets hot), light (sun appears to be

shining)

C 400

What form(s) of energy could you represent?

C 500

Chemical (food we eat and how our body stores),

Mechanical (whenever we move), Electrical (brain

impulses), Sound (talking), Thermal (body heat)

C 500

Compare and contrast thermal energy and

temperature when it comes to the size of an object.

D 100

Since thermal energy is the total energy of the particles in an object, size does matter for TE. The larger the object, the greater the TE. Temperature, being the average energy of

the particles, is not influenced by the size of the object.

D 100

No more energy can be removed from matter at what temperature?

D 200

Absolute Zero (0 K, -273 °C, -460 °F)

D 200

The creation of wind at the beach is best explained by

which method of heat transfer?

D 300

Convection best explains the creation of wind at the beach, as

warm air rises and cooler air is pushed

down.

D 300

A thermometer, such as the one above, depends on which method of heat

transfer?

D 400

A thermometer uses conduction.

D 400

Describe how a refrigerator can cool

food down.

D 500

Thermal energy from the warmer food is transferred to

the cooler air in the fridge, causing the food to get

cooler, and the air to get warmer.

D 500

What conversion takes place when natural gas is used to heat a pot of

water?

E 100

The chemical energy in the natural gas is

converted into thermal energy.

E 100

When you rub your hands together on a

cold day, what conversion is taking

place?

E 200

Mechanical Energy is being converted into

thermal energy, through friction.

E 200

The law of conservation of energy says what

about energy?

E 300

Energy cannot be created or destroyed.

E 300

Describe 3 energy conversions which take place

in the appliance above.

E 400

Electrical energy is converted into

electromagnetic/light, sound, and thermal energy. Light and sound energy are also converted into thermal

energy.

E 400

Describe conversions from 3 different sources which take place in the above diagram.

E 500

Chemical energy is converted into mechanical, electrical, and

thermal energy. Electrical energy is converted into light

and thermal energy. Mechanical energy is

converted into thermal and sound energy. Light energy is

converted into chemical energy. Nuclear energy is

converted into light energy.E 500

Fossil fuels, such as coal, are examples of which form

of energy?

F 100

Fossil fuels are examples of chemical

energy

F 100

When a fossil fuel is burned, what happens to its chemical energy?

F 200

The chemical energy is converted into thermal

energy, as well as possibly light and sound energy.

F 200

What form of energy does a spinning turbine

have?

F 300

A spinning turbine has mechanical energy.

F 300

Most power plants have the same basic procedure to

“create” electricity by heating water. What are the

general steps to the procedure after the water

boils?

F 400

Steam rises, which turns a turbine. The spinning

turbine turns a generator, which “creates” the

electricity.

F 400

Other than burning fossil fuels like coal, name 3 other ways to create steam for a

power plant.

F 500

1)Burn biomass products

2)Use the nuclear energy of radioactive materials, like

uranium

3)Use the thermal energy of Earth

4)Use energy from the sun, focused with mirrors
