3
Energy Define Energy and what is its unit?
4
Energy Energy is the ability to do Work, measured in Joules.
5
What are the 2 kinds of energy? Define them.
6
Kinetic Potential Kinetic energy (the energy of motion) and Potential energy (stored energy).
7
What are 2 ways that you can increase an object’s Potential Energy?
8
By increasing the height of the object or by stretching it.
9
Kinetic Energy = ½ x Mass x Velocity 2 Which one has the greatest KE? a)2,000kg car going 2m/s b)100kg person running 10m/s c)40kg cheetah running 30m/s

11
What is Energy Conversion?
12
Changing the form of energy (Potential energy can be converted into Kinetic energy).
13
Law of Conservation What does the Law of Conservation state?
14
Law of Conservation The Law of Conservation states that energy can not be created or destroyed.
15
Explain where the Kinetic energy and potential energy are both at their highest and lowest in the diagram.
16
Kinetic Potential Kinetic energy is highest at point 3 and lowest at 1 and 5. Potential energy is highest at points 1 and 5 and lowest.
17
Albert Einstein’s theory of relativity states that energy and matter are related. What is the formula he used to express this idea?
18
Back to Menu Final Jeopardy Emc 2 E = m x c 2 E m c Einstein’s theory states that the Energy (E) of an object equals its Mass (m) times the speed of light (c) squared.
19
Power What is the definition of Power? ( Not the equation )
20
Power Power is the rate at which energy is transferred or converted.
21
What is the ‘advanced’ formula for Power and its unit?
22
Power = Force x Distance Time Power is measured in Watts.
23
5,436 Joules 18 seconds A tow truck uses 5,436 Joules to lift a car over 18 seconds. What is the Power of the tow truck?
24
Power = Work Time Power = 5,436J 18s Power = 302W
25
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.
26
Back to Menu Final Jeopardy Which has more Power? Power = 10N x 0.2m 2s Power = 1W Power = 20N x 0.5m 5s Power = 2W
27
What 3 fuels are known as Fossil Fuels?
28
The 3 Fossil Fuels are Coal, Petroleum, and Natural Gas.
29
How does the Sun produce energy?
30
The Sun produces energy through Nuclear Fusion by fusing 2 Hydrogen atoms together.
31
Explain how Fossil Fuels contain energy that came from the Sun.
32
Fossil Fuels come from once-living organisms (plants & animals) who lived off energy created by the Sun.
33
Pennsylvania has a large amount of a certain fossil fuel. What does that tell you about its prehistoric climate?
34
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. Back to Menu Final Jeopardy
35
What is Mechanical Energy?
36
Energy associated with motion or position of an object.
38
Nuclear Energy can be released through Nuclear Fusion (Sun) or Nuclear Fission (atomic bomb).
39
What form of energy travels in waves? What type of heat transfer is this?
40
Electromagnetic energy. This type of heat transfer is called Radiation.
41
Name and describe the other 3 forms of energy.
42
Chemical: Chemical: potential energy stored in chemical bonds (food). Thermal: Thermal: total energy in the particles of an object. Electrical: Electrical: energy stored in moving electric charges. Back to Menu Final Jeopardy

One __________ is equal to _______ watts. This unit is used to describe the _____ of ____. power33,000horsepower 746 carsteam engine WatthorseJoule work
45
Watt steam enginework horse 33,000 horsepower746 powercar 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.
