Final Jeopardy
6
Motion for 100

• What is the distance traveled at the 4 s mark?
• 40 m ( or 2 m)

7
Motion for 200

• Draw a distance-time graph for an object that is
  not moving at all.
• Straight horizontal line on a distance vs. time
  graph

8
Motion for 300

• Draw a speed-time graph for an object traveling
  at a constant speed.
• Graph should be a straight horizontal line
  indicating the same speed over a period of time
  for a speed-time graph.

9
Motion for 400

• Draw a distance-time graph for an object
  traveling at a constant speed.
• Graph should be a straight line slanted up and to
  the right or down and to the right (with distance
  on the y-axis and time on the x-axis)

10
Motion for 500

• Draw a speed-time graph showing an object
  slowing down.
• Graph should be a slanted line going down and to
  the right on a speed-time graph.

11
Forces for 100

• Which of the following would require the
  greatest force a large truck accelerating at 5
  m/s/s, a small stone accelerating at 6 m/s/s, or
  a person accelerating at 5.5 m/s/s. Explain your
  answer.
• The truck because its greater mass has a greater
  effect on the force it would exert than the
  slightly higher accelerations of the person and
  the stone.

12
Forces for 200

• Explain why a kicker can sometimes fly backward
  when kicking another person. Hint- Newtons 3rd
  Law.
• The action force is the kick, while the equal and
  opposite reaction is the body of the person whos
  being kicked pushing back on the kicker.

13
Forces for 300

• Why are larger people unable to move as quickly
  as lighter people?
• More force is required to accelerate a heavier
  mass.

14
Forces for 400

• Explain why your body moves backward when a car
  first takes off.
• Your body is at rest and attempts to remain at
  rest (due to your inertia).

15
Forces for 500

• Markie Suzie conduct an experiment to
  determine how mass affects the force needed to
  move that object. They choose to push objects up
  a ramp. They both believe that heavier objects
  will require more force. How should they design
  the experiment? What is 1 constant? May give
  answer verbally.
• Design- Push objects of different masses up a
  ramp and measure the force exerted.
• Constants- Same ramp height/incline, same
  acceleration, same object, same position of
  release on the ramp

16
Work Machines for 100

• Which class of lever is the input force opposite
  the direction of the output force? Is this the
  class that pliers belong to? How does the load
  weight (output force) compare the input force for
  1st and 2nd class levers?
• 1st class
• Yes, b/c the fulcrum is in the middle.
• Load weight is greater than the input force.

17
Work Machines for 200

• How can you increase the M.A. of a pulley
  system?
• Add more pulleys to create more sections of rope.

18
Work Machines for 300

• Suppose the input force for a screwdriver is 15
  N, then which of the following could be the
  output force 0 N, 10 N, 15 N, or 30 N? Also,
  how does the M.A. compare to 1?
• 30 N (output is greater than input, M.A. gt 1)

19
Work Machines for 400

• Which of the following would be an example of a
  compound machine scissors, ruler, wheelbarrow,
  or door stopper? CHOOSE ONE and list 2 types of
  simple machines that make up that compound
  machine.
• Wheelbarrow wheel axle and lever (2nd class)
• Scissors Wedge 1st class lever

20
Work Machines for 500

• Explain how a screwdriver works (in terms of
  input and output force as well as input and
  output distance).
• The input force over the wheel (handle) travels a
  greater distance than the larger output force
  over the axle (metal rod).

21
Energy for 300

• If your throw a ball up in the air, how do the
  PE and KE change as the ball goes up and then
  comes back down? Explain your answer.
• PE increases as the ball goes up because it is
  higher off of the ground while the KE decreases
  until the ball starts to gain speed as it goes
  back toward the ground. As the ball goes down,
  the KE increases and the PE decreases (lower
  height).

22
Forces

• Newtons Cradle demonstrates how momentum (and
  energy) can be transferred between objects.
  However, after a period of time, the metal
  spheres do not bounce as high and eventually stop
  moving. Explain why this occurs.
• Friction between the spheres and strings as well
  as the air around the cradle cause the momentum
  and energy to be lost.
