B.
Use the diagram above to answer
questions 20 – 25.
20. At what letter(s) is the kinetic energy
greatest as the dolphin jumps? ___D_
21. At what letter(s) is the potential energy
greatest as the dolphin jumps? ___B__
22. At what letter(s) is the kinetic energy
the least as the dolphin jumps? __B__
23. At what letter(s) is the potential energy
the least as the dolphin jumps? __D__
24. If the dolphin could move from point D
to point B the _potential__energy would
increase and the _kinetic___ energy
would decrease.
25. As the dolphin moves from point B to
point D, the __kinetic ___energy is
increasing and the _ potential __ energy
is decreasing.
How would the potential and kinetic
energy change from diagram A to
diagram B above?
Potential goes up while the kinetic goes
down.
Identify the type of potential energy shown in each situation.
26. Electrostatic
27. Chemical
Rubbing your feet on carpet, touching a door knob and
getting a shock.
Building a circuit and using a battery to light a bulb.
28.Elastic
Jumping on a trampoline.
29.Gravitational
A skydiver jumping from an airplane.
30.Magnetic
Picking up a paper clip using a magnet.
31. Nuclear
Using uranium to produce power at a nuclear power
plant.
Identify the type of kinetic energy shown in each situation.
32.Thermal
Warmth produced by a candle.
33.Sound
A musician strums a guitar and plays a song.
34. Electromagnetic
Sunlight streaming through you window in the morning.
35.Mechanical
A snowball rolling down a hill.
36.Electrical
Lightning streaking across a stormy sky.
37. What is the highest position the pendulum will most likely reach on the other side,
if it is released from point 1?
Position 5 if there were no friction. With friction, the highest it will get would be
position 4.
38. Could the pendulum ever reach a point
higher than position 5? Why or why not.
1.
5.
2.
4.
3.
No because the law of conservation of energy
says we cannot create or destroy energy. The
original PE is equal to the height of position 1,
so it can never reach a height higher than its
original PE.
