Momentous Occasion 2
• A bowling ball with a mass of 10 kg hits a
stationary bowling ball with a mass of 5 kg
and gives up all of its momentum to the 5 kg
bowling ball.
• The 10 kg ball was going 2 m/s.
• What will the speed of the 5 kg ball be?
Back
3.
Momentous Occasion 2
• It will have twice the speed because
momentum is conserved.
• Back
4.
Momentous Occasion 3
• Does anything on earth have zero momentum
if you use the sun as a frame of reference?
• Back
8.
Gimme a Problem 2
• A Yankees fan is being chased by a Red Sox fan
in the streets of Boston. The Yankees fan is
running at 30 km/hr. He is chased from 6:30
pm until 7:00 pm. How far did he get chased?

Moving Right Along 1
• An airplane travels at a rate of 400 km/hr. Its
destination is 1200 km away. What is the
flight duration?
• If the plane has to fly into a wind that
averages 100 km/hr, what is the new flight
duration?
16.
Momentous Occasion 1
What is the momentum equation?
What does momentum measure?
17.
Momentous Occasion 1
• Mass times velocity
• How hard it is to stop a moving object
18.
Moving Right Along 4
• If the earth orbits around the sun at the same
speed all the time, is it accelerating? Why/
why not?
19.
Moving Right Along 4
• Because it is changing direction
20.
I was Framed 1
• If you are chasing a friend on your bike and
going at the same speed and you use your
bike as a frame of reference, is your friend
moving?
22.
I Was Framed 2
• If you put a slinky on an escalator that is going
up and the slinky stays there doing what
slinkys are supposed to do (slink)….
• …then: What is its speed, in m/s?
• Ps: The escalator stairs move at .8 m/s…
23.
I Was Framed 2
• Using the earth as a frame of reference, its
speed is 0 m/s
• Using the escalator as a frame of reference, its
speed is .8 m/s
24.
I Was Framed 3
• If you are on a moving sidewalk that is going
1.5 m/s and you walk with it at the same
speed and in the same direction as it moves,
what is your speed?
25.
I Was Framed 3
• 3 m/s using the earth as a frame of reference
26.
I Was Framed 4
• A deep sea diver can lose track of which way is
up.
• What can she use as a frame of reference if
everything around her is nothing but
darkness?
Clipping is a handy way to collect and organize the most important slides from a presentation. You can keep your great finds in clipboards organized around topics.
