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
• This is the definition of PE.
100
Potential Energy
200
• Give 2 types of Potential Energy
Potential Energy
• This is the equation for PE.
300
Potential Energy
400
• What is the PE of a 100kg ball that is
resting on a 50m high shelf?
Potential Energy
500
• 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
• List 2 examples of KE.
200
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?
Work
100 Response
• Work is the product of a
force applied to an
object and the distance
it moves.
Work
200 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 d
200J = F x 5m
200J/5m = F
40N = F
Potential Energy
100 Response
• Stored energy
Potential Energy
200 Response
• Elastic PE
• Gravitational PE
Potential Energy
300 Response
• PE = m g h
Potential Energy
400 Response
• PE= m g h
2
• = 100kg (10m/s ) (50m)
•
= 50,000 J
Potential Energy
500 Response
• PE = m g h
2
500J= 25kg (10m/s ) h
500/250 = h
250m = h
Kinetic Energy
100 Response
• Energy of motion
Kinetic Energy
200 Response
• Anything moving
Kinetic Energy
300 Response
• KE = ½ m
2
v
Kinetic Energy
400 Response
• KE = ½ (10kg) (2m/s)2
= .5 (10) (4)
= 20 J
Kinetic Energy
500 Response
• KE = ½ m v2
2
100J = .5 m 5
100J = .5 m 25
100/12.5 = m
8kg = m
Power
100 Response
Power is the amount of
work done over a
period of time.
Power
200 Response
• Watt or kilowatt
• w or kw
Power
300 Response
• P = work/time
Or
P = F d/t
•
Power
400 Response
• P = work/time
= 200J/10s
= 20 Watts
Power
500 Response
• P = work/time
60W = 600J/t
t = 600/60
t = 10s
Energy
100 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
