Work 100

•This is the definition of work.

Work 200

•This is the unit for work.

Work 300

•In order for work to be done these 2 things must take place.

Work 400

•If a force of 50N is used to lift a book 10m, How much work is done?

Work 500• How much force was necessary to

move a brick 5m if 200J of work was done?

Potential Energy 100

• This is the definition of PE.


• Give 2 types of Potential Energy


• This is the equation for PE.


• What is the PE of a 100kg ball that is resting on a 50m high shelf?


• How high must a 25kg ball be resting if its Potential Energy is 500J?

Kinetic Energy 100• This is the definition of KE.

Kinetic Energy 200• List 2 examples of KE.

Kinetic Energy 300• This is the equation for Kinetic

Energy.

Kinetic Energy 400• What is the KE of a 10kg ball

which is rolling down a hill at a speed of 2m/s?

Kinetic Energy 500• What is the mass of a ball that has

100J of KE and is moving at a velocity of 5m/s?

Power 100• This is the definition of Power.

Power 200• This is the unit for Power.

Power 300

•This is the equation for power.

Power 400

•What is the power of a light bulb that does 200J of work in 10s?

Power 500

•How long does a 60watt bulb need to be on to do 600J of work?

Energy 100

•This is the Law of Conservation of Energy.

Energy 200

•Give 1 example of a fossil fuel.

Energy 300

•Visible light is an example of what type of energy?

Energy 400

•When you rub your hands together of a cold day, you use friction to convert ___________ energy into ___________ energy.

Energy 500

•What type of conversion is taking place when natural gas is used to heat water?

Work100 Response

•Work is the product of a force applied to an object and the distance it moves.

Work200 Response

•Joule (J)

Work 300 Response

•Force must be applied on an object and the object must move.

Work 400 Response

•W = F x d = 50N x 10m = 500J

Work 500 Response

•W = F x d200J = F x 5m 200J/5m = F 40N = F

Potential Energy100 Response

•Stored energy

Potential Energy 200 Response

•Elastic PE•Gravitational PE


•PE = m g h


•PE= m g h• = 100kg (10m/s2) (50m)

• = 50,000 J


•PE = m g h 500J= 25kg (10m/s2) h500/250 = h 250m = h

Kinetic Energy100 Response

•Energy of motion

Kinetic Energy 200 Response

•Anything moving


•KE = ½ m v2


•KE = ½ (10kg) (2m/s)2 = .5 (10) (4) = 20 J


•KE = ½ m v2

100J = .5 m 52 100J = .5 m 25100/12.5 = m 8kg = m

Power100 Response

Power is the amount of work done over a

period of time.

Power200 Response

•Watt or kilowatt• w or kw

Power 300 Response

• P = work/timeOr

P = F d/t•

Power400 Response

•P = work/time = 200J/10s = 20 Watts

Power 500 Response

•P = work/time60W = 600J/t t = 600/60 t = 10s

Energy100 Response

•Energy can not be created or destroyed but may be changed from one form to another.

Energy 200 Response

•Oil, gasoline, coal

Energy 300 Response

•Electromagnetic

Energy 400 Response

•You use friction to convert mechanical energy into

thermal energy

Category 5 500 Response

•CHEMICAL ENERGY is converted to

THERMAL ENERGY
