Define Energy and what is its unit?

Energy is the ability to do Work, measured in Joules.

What are the 2 kinds of energy? Define them.

Kinetic energy (the energy of motion) and Potential energy (stored energy).

What are 2 ways that you can increase an object’s

Potential Energy?

By increasing the height of the object or by stretching it.

Kinetic Energy = ½ x Mass x Velocity2

Which one has the greatest KE?a) 2,000kg car going 2m/sb) 100kg person running 10m/sc) 40kg cheetah running 30m/s

Kinetic Energy = ½ x Mass x Velocity2

Which one has the greatest KE?a) 2,000kg car going 2m/s = 4,000Jb) 100kg person running 10m/s = 5,000Jc) 40kg cheetah running 30m/s = 18,000J

What is Energy Conversion?

Changing the form of energy (Potential energy

can be converted into Kinetic energy).

What does the Law of Conservation state?

The Law of Conservation states that

energy can not be created or destroyed.

Explain where the Kinetic energy and potential energy are both at their

highest and lowest in the diagram.

DAILY DOUBLE!

Kinetic energy is highest at point 3 and lowest at 1 and 5. Potential energy is highest at points 1 and 5 and lowest .

Albert Einstein’s theory of relativity states that energy

and matter are related. What is the formula he used to

express this idea?

E = m x c2

Einstein’s theory states that the Energy (E) of an object equals its Mass (m) times the speed of

light (c) squared.

What is the definition of Power? (Not the equation)

Power is the rate at which energy is transferred or converted.

What is the ‘advanced’ formula for Power and its unit?

Power = Force x Distance Time

Power is measured in Watts.

A tow truck uses 5,436 Joules to lift a car over 18 seconds. What is the Power of the tow truck?

Power = Work Time

Power = 5,436J18s

Power = 302W

Which has more Power?

A drill that can put a 10N nail 0.2m into a block of

wood in 2 seconds.

A hammer that can put a 20N nail 0.5m into wood

in 5 seconds.

Final Jeopardy

Which has more Power?

Power = 10N x 0.2m 2s

Power = 1W

Power = 20N x 0.5m 5s

Power = 2W

What 3 fuels are known as Fossil Fuels?

The 3 Fossil Fuels are Coal, Petroleum, and Natural Gas.

How does the Sun produce energy?

The Sun produces energy through Nuclear Fusion by fusing 2 Hydrogen atoms together.

Explain how Fossil Fuels contain energy that came

from the Sun.

Fossil Fuels come from once-living organisms

(plants & animals) who lived off energy created

by the Sun.

Pennsylvania has a large amount of a certain fossil

fuel. What does that tell you about its prehistoric climate?

PA produces 50 million tons of coal a year! Coal comes from plants buried in swamps over millions of years. PA used to have a

swamp-like environment.

What is Mechanical Energy?

Energy associated with motion or position of an

object.

What is one way Nuclear Energy can be released?

5 Point Bonus: What is the second way?

Nuclear Energy can be released through Nuclear Fusion (Sun) or Nuclear Fission (atomic bomb).

What form of energy travels in waves? What type

of heat transfer is this?

Electromagnetic energy. This type of heat transfer is

called Radiation.

Name and describe the other 3 forms of energy.

Chemical: potential energy stored in chemical bonds (food).

Thermal: total energy in the particles of an object.

Electrical: energy stored in moving electric charges.

James Watt wanted to advertise his improved steam engine. He compared the work it could

do to that of a horse lifting a 33,000 pound weight a certain distance in a certain time. One horsepower is equal to 746 watts. This unit is

used to describe the power of car.
