How do you calculate the
Gravitational potential Energy?
A 60 Kg diver jumps from a 10 m platform.
What is their Eg at the top of the platform?
5880 J
What is the formula for
calculating the amount of work
done to an object?
How much work is done must an engine of a
car do if it exerts a force of 500 N at a constant
speed over a distance of 30 m?
15,000 J
What is the formula for kinetic
energy?
A 1.5 Kg kitten is standing on top of a 2 m high
fence. The kittens Eg is 29.4 J. Assume all
energy is transferred. What is her speed when
she hits the ground?
6.3 m/s
What is the work-energy
relationship?
Hint – look in your unit 1
Energy Notes
What is the formula for
calculating the Elastic potential
energy?
How much elastic potential would be stored in
a spring if it was stretched 0 to 0.4 m? (spring
constant = 8 N/m)
0.64 J
What is the formula for power?
How many joules does your 1600 W blow drier
transfer if you dry your hair for 5 minutes?
480,000 J
What is the difference between a
transverse and longitudinal wave?
What are examples of each?
(water/slinky? light? Sound?)
Interference of waves occur in
what type of wave? Explain what
happens during interference.
What is the difference between a
node and anti-node?
What is the Doppler effect?
How do you calculate Doppler
effect?
You are stopped at a traffic light. An
ambulence approaches you from behind with a
speed of 18 m/s. The siren produces a sound
frequecy of 955 Hz. The speed of sound is 343
m/s. What is the frequency you hear?
1007 Hz
What is a sonic boom?
What is the average hearing
range? What is it measured in?
In what mediums can sound
waves travel? Light waves?
What is a beat frequency?
If one frequency is 450 Hz and
the beat frequency is 5 Hz. What
are the two potential second
frequencies?
445 or 455 Hz Hz

If your answer to that question is No, ASK someone
how to use it. It will help you on the final exam!
When we see an object as red,
what is really happening?
What are the primary colors of
light?
Why are large bodies of water
greenish blue?
If I shine red light on a blue
board, what color would it
appear?
What does the law of reflection
tell us about incident and
reflected angles?
If you have two plane mirrors set
up at a certain angle, how can
you determine the number of
images without counting all of
them?
What type of image do you get
with a plane mirror?
What does a convex mirror do to
light rays? Converge or diverge?
What does a concave mirror do to
light rays? Converge or diverge?
What does a diverging lens do to
light rays?
What does a converging lens do
to light rays?
How does the Radius of Curvature
(C) relate to the focal point (f)?
What are the lens and mirror
equations and what do the
variables stand for?
What type of particle flows in an
electrical current?
What do like charges do with each
other & what do opposite charges
do with each other?
How does something become
positively and negatively charged?
What does the term polarized
mean?
What is the difference between
charging by induction and
conduction?
What are the unit of…

Law?
What voltage is applied to a 4.0 Ω
resistor if the current is 1.5 A?
6V
What is the formula for electronic
power?
A car battery causes a current of 2.0 A
through a lamp. It produces 12 V across it.
What the power used by the lamp?
24 W
What are the characteristics of a
series circuit?
What are the characteristics of a
parallel circuit?
Good Luck and may the
Phorce be with you !
