Question

name: _
kinetic or potential energy
next to each description, write the type of energy it describes: kinetic or potential

1. a car speeding on the freeway _
2. a truck parked on the driveway _
3. an apple hanging from a tree _
4. a glass of water on the table _
5. a rubber band zinged from your finger _
6. a boy climbing the stairs _
7. a ball at the edge of a cliff _
8. a bird flying _
9. a black light turned off _
10. a stretched rubber band _

describe what you see in the picture. is it showing kinetic or potential energy? explain your answer _

Explanation:

Kinetic energy is energy of motion. Potential energy is stored energy.

1. A car speeding has motion, so kinetic energy.
2. A parked truck is stationary, has potential energy (gravitational).
3. An apple hanging has potential (gravitational).
4. A glass of water on table has potential (gravitational).
5. A rubber - band zinged is in motion, kinetic energy.
6. A boy climbing has motion, kinetic energy.
7. A ball at cliff edge has potential (gravitational).
8. A flying bird has motion, kinetic energy.
9. A turned - off black light has no motion or energy release, not applicable here in terms of kinetic or potential in a relevant sense.
10. A stretched rubber band has elastic potential energy. For the baseball player, if ready to swing, has potential (elastic in muscles, gravitational due to position); if swinging, has kinetic energy.

Answer:

1. Kinetic
2. Potential
3. Potential
4. Potential
5. Kinetic
6. Kinetic
7. Potential
8. Kinetic
9. N/A
10. Potential

Baseball player: If ready to swing - Potential; If swinging - Kinetic
