Graphs for 500
Explain the acceleration for each
segment of the graph below.
Speed
(m/s)
Accelerates from 0 to 10 in 2 seconds, or 6m/s/s.
Goes a constant speed (10 m/s) for 4 seconds.
Then decelerates from 10 m/s to 0 m/s. Then
stops completely for 2 seconds.
BACK
Motion for 100
How can you tell if
an object is in
motion?
If the distance between an object
and its reference point changes.
BACK
Motion for 200
If a car drives 80 meters
in 10 seconds, what is
it’s speed? Don’t forget
units.
Speed = 80m/10s = 8 m/s

Motion 300
A passenger walks towards the
rear of a moving train. What is
her motion in relation to a
reference point on the train?
Backwards in relation to a
reference point on the train.

Pressure for 100
How do snowshoes
make it easier to walk on
snow?
Snow shoes increase surface area
which spreads out the amount of
force you put on the snow
BACK

of a substance is
30g/cm³, and its mass is
1200 grams. What is the
volume of this sample?

Pressure for 300
A student has two containers. Container A holds 1 liter
of liquid. Container B holds two liters of liquid. Both
containers are filled with same liquid. Are the densities
of the two liquids equal or unequal?
The density of the liquid in a container A is equal to the
density of container B.
BACK
Pressure for 400
What is the density of a solid
1cm long, 0.5cm wide, and
2cm high, if the mass is 6
grams?( remember volume is
length x width x height)

BACK
Pressure for 500
A rock has a density of 45g/ml and
a mass of 90g. What is it’s
volume?
Density = mass ÷ volume
Volume = Mass ÷ density
Volume = 90g ÷ 45g/mL

Final Jeopardy
A
ladybug is creeping down a sidewalk
at 1 m/s. Sometime later, it’s speeding
at 5 m/s. This could have happened if
the lady bug accelerated at 1 m/s/s for 4
seconds. Is this the only way that the
increase in speed could have
happened? Explain.
possibilities:
1 m/s/s for 4 s,
2 m/s/s for 2 s, 4 m/s/s for 1 s
