Answer 1

1. The object that has potential energy is:
**D) can of gasoline**
(The can of gasoline has potential energy due to its chemical energy and its ability to be used as fuel.)

2. The correct statement about energy is:
**B) Energy can be changed from one form to another.**
(This reflects the principle of conservation of energy, where energy can transform from one type to another, but it cannot be created or destroyed.)

3. The object that has kinetic energy is:
**C) soccer ball flying through goalposts**
