Decide whether each of the following are A) potential energy or B) kinetic energy:
21. A rock sitting at the edge of a cliff
22. A baseball thrown by a pitcher
23. A downhill skier traveling down a hill
24. A stick of dynamite
25. An asteroid falling to earth
26. A car traveling down the road.
27. A golf ball sitting on a tee before it is struck.
Decide if each statement is true or false:
28. Objects that have potential energy do not use their energy until they move. That is why it is called “potential”
energy.
29. Energy appears in different forms, such as motion and heat.
30. Energy cannot travel in different forms, such as light, sound or electricity.
31. Energy can be transferred from one system to another: thermally energy - when a cooler object is in contact with a
warmer one;
32. Energy can be transferred from one system to another: mechanically, when two objects push or pull on each other
over a distance;
33. Energy can be transferred from one system to another: electrically, when an electrical source such as a battery or
generator is connected in a complete circuit to an electrical device.
34. To produce electricity, a heat source is needed to create the conditions in which electrical currents form.
