some of the links from the first page are messed up. I recommend you just go through it in order I also meant cm squared on the pressure units, slide 23

destination is 1200 km away. What is the
flight duration?

averages 100 km/hr, what is the new flight
duration?

3. Moving Right Along 1

5. Moving Right Along 2
• Speed is just distance/time

6. Moving Right Along 3
• On a distance-time graph, if the graph line
curves, then you know the object being
graphed has _________________?

7. Moving Right Along 3
• accelerated

8. Moving Right Along 4
What is the momentum equation?
What does momentum measure?

9. Moving Right Along 4
• Mass times velocity
• How hard it is to stop a moving object

10. Moving Right Along 5
• If the earth orbits around the sun at the same
speed all the time, is it accelerating? Why/
why not?

11. Moving Right Along 5
• Because it is changing direction

12. May the ma be with you 1
• When forces are unbalanced when acting
upon an object, the object will do what?

13. May the ma be with you 1
• accelerate

14. May the ma be with you 2
• Objects are hard to get moving because of this
property of matter
• This property of matter is measured by
measuring the object’s __________

15. May the ma be with you 2
• Inertia
• mass

16. May the ma be with you 3
• Name the 4 types of friction

17. May the ma be with you 3
• Static
• Moving
• Rolling
• Fluid
• Sliding

18. May the ma be with you 4
• Newton’s Universal Law of Gravitation states
that gravity depends on an object’s
___________ and ___________ .

19. May the ma be with you 4
• Mass and distance

20. May the ma be with you 5
• Use 2 of Newton’s 3 Laws of motion to explain
what is not valid with this video clip.

21. May the ma be with you 5
• The little droids should have kept moving with
the spaceships. (1st Law. In space, there’s no
outside force acting on them b/c there’ no air in
space)
• When the little droids get flown back it implies
they are reacting to a force from air that doesn’t
exist in space. (air pushes, droid gets pushed
back…however no force pair exists without the
air…not following Newton’s 3rd law)

22. Go with the flow, yo 1
• Equations for this chapter are:
• Pressure =? And units?
• Density= ? And Units?
• (four answers must be correct!)

23. Go with the flow, yo 1
• Pressure = force/area
• Units= n/cm3
• Density= mass/volume
• Density= g/mL

24. Go with the flow, yo 2
• Name the 3 things you can do to a container
of gas to get the gas to change its pressure

25. Go with the flow, yo 2
• Heat it up
• Make container smaller
• Pump more fluid into the container

26. Go with the flow, yo 3
• Why does buoyancy exist in fluids?

27. Go with the flow, yo 3
• Because pressure is greater with depth, the
greater pressure something experiences at its
base, which pushes up on it.

28. Go with the flow, yo 4
• Which soda has more buoyant force acting on
it?

29. Go with the flow, yo 4
• Regular coke

30. Go with the flow, yo 5
• When I was a kid, my best friend’s mom would
smoke cigarettes all the time. When she
drove us somewhere, she would crack the
window open a little so the smoke could
escape. Would more smoke get sucked out if
the car was parked, or if it was going slow, or
going fast?
• What principle does this show?

31. Go with the flow, yo 5
• Faster
• Bernoulli’s principle

32. Simply working it 1
• Equations for the chapter:
• Work =? Units=?
• Power=? Units=?
• Mechanical Advantage= ? Units=?
• Efficiency =? Units =?

33. Simply working it 2
• List the six simple machines’ names

34. Simply working it 2
• Lever
• Pulley
• Screw
• Inclined plane
• Wheel and axle
• Wedge

35. Simply working it 3
• A single fixed pulley multiplies force as it
changes the direction of the force. (T/F?)

36. Simply working it 3
• False
• Only changes direction (ma=1)

37. Simply working it 4
• The output distance of a machine with an MA
of 5 will be
• A) 5 times longer than input distance
• B) 5 times shorter than input distance
• C) the same as input distance
• D) greater, but by how much depends on
friction

38. Simply working it 4
• B

39. Simply working it 5
• Name the classes of these levers:
• Scissors
• Hockey Stick
• Wheelbarrow
• Pliers

40. Simply working it 5
• Scissors 1st
• Hockey Stick 3rd
• Wheelbarrow 2nd
• Pliers 1st

41. Energizer Bunny 1
• List which of the five forms of energy are
potential
• Then, list which of the five forms of energy are
kinetic

42. Energizer Bunny 1
• Potential: nuclear and chemical
• Kinetic: heat, electromagnetic, mechanical

43. Energizer Bunny 2
• If an object has a mass of 50 kg and is moving
at 2 m/s, what is its kinetic energy?
• If the same object is held 3 meters high above
the ground what is its gravitational potential
energy?

44. Energizer Bunny 2
• 100 J
• 1470 J

45. Energizer Bunny 3
• After the car is lifted up the first hill, a
rollercoaster runs on gravity. If the energy of
the coaster is equal to its starting GPE, why
must the rest of the hills be lower in height
than the first?

46. Energizer Bunny 3
• Because of the law of conservation of energy,
the coaster’s height on successive hills can
never be higher than the starting, otherwise,
it would be gaining energy.
• In fact, it loses a lot of energy as noise and
heat due to friction as it travels: requiring
even lower hills later

47. Energizer Bunny 4
• Describe an energy conversion that involves
turning mechanical energy into heat.

48. Energizer Bunny 4
• Rubbing hands

49. Energizer Bunny 5
• If a ball is thrown upward into the air at a
release height of 2 meters, goes up, then falls
back to earth, its speed at its starting height is:
• A) greater than the speed thrown at (because
of gravity)
• B)less than the speed thrown at (because of
friction
• C) equal to the speed thrown at (just because)

50. Energizer Bunny 5
• C: KE at that height is equal (what you put
into system is what you get out…..energy is
conserved.)
