Volume is measured using this
tool and can be measured in
these 2 units.
What are graduated cylinders, mL
3
& cm ?
If you have 11km, you have
this many Dm and this many
dm.
What 1100Dm and 110,000dm?
This metric prefix means
2
10 .
What is Hecto?
The metric prefixes in
order from smallest to
biggest.
What is milli, centi, deci, Deca, hecto
kilo?
If a cube is .1cm on a side then its
3
in m is this.
What is 1x10-9 m3?
Speed is different from velocity
in this way.
What is speed lacks a
direction and velocity has
direction?
To calculate velocity you need
these 3 pieces of data.
What is distance, time and
direction?
This formula makes sure that you
get the sign right when you
calculate acceleration.
What is a = vf - vi?
t
If a car goes from 50 m/s to 10
m/s in 5s what is the car’s
acceleration?
What is -8 m/s/s?
A car goes 30m/s for an
hour. How far does the car
go?
What is 108,000 meters?
If an ice skater has a mass
of 65kg and the ice is able
to push back with 650N,
what will happen to the
girl? Which law is this?
What is the ice can support her?
F=ma= 65kg x 9.8m/s/s = 637 N
Newton’s 3rd Law
Newton’s first law states this and
is strongly associated with this
vocab. word.
What is acceleration is inversely
proportional to mass?
What is inertia?
If a 200N force is applied to a 6
kg box, what will the acceleration
of the box be?
What is 33.3 m/s/s?
If a book is 4.4kg and is moved with
acceleration 2.5m/s/s for 3m, how
much work is done?
What is 33 Joules?
F=ma w=Fd
W=mad
W=(4.4kg)(3m)(2.5m/s/s)
A 2kg pendulum is held at the end
of its swing. It is .6m from the
bottom of its swing. What velocity
will the bob have when it reaches
the bottom of its swing?
What is 3.43 m/s?
2
mgh=1/2mv
2gh=v2
V= sq root(2x 9.8m/s/s x .6m)
V= sq root (11.76m2/s2)
V= 3.43 m/s
When calculating heat transfer
the c stands for what?
What is specific heat?
How much heat it takes to raise 1g of
a substance by 1 degree C?
The formula for heat transfer is
what?
What is: Q=mcΔt
where you use tf-ti for the
temp change?
A cup of boiling water or the Pacific
Ocean holds more heat and why.
What is the ocean because you are
multiplying by mass?
The mass of the water in the cup is
very small, but the ocean’s mass is
vast!
A cup of water with mass 22g goes
from 89 degrees C to 42 degrees C.
What the energy absorbed by the
water?
What is -1034 calories?
Q=mc(tf-ti)
Q=22g (1cal/g deg C) ( 42-89 deg C)
If aluminum’s specific heat is
0.215 cal/g deg C and you have
2.1g of it going from 10deg C to
50deg C, how much heat is being
absorbed by the aluminum?
What 18.06 cal?
Q=mc(tf-ti)=(2.1g).215cal(50-10deg C)
2.1x.215x40
Latitude is so important
for predicting climate
because….
What is the sun hits the earth at
different angles depending on
latitude?
Our native biome is called…
What is coniferous forest?
An ice cube floats on water
for this reason.
What is ice is less dense than
liquid water?
This generally goes on the x-axis
and this on the y-axis.
What is independent (M)
variable on the x-axis? What is
dependent (R) variable on the
y-axis?
In Hawaii I drop a rock into a cave
and it takes 3.1s to hit the bottom.
The cave is __deep!
What is 47.1m?
D= ½ gt2
2
D= ½ (9.8 m/s/s)(3.1s)
