Question

determine whether each situation is an example of potential or kinetic energy
a trophy sitting on shelf in the display case. choose...
a football player running with the ball. choose...
a second grader doing a cartwheel. choose...
a merry - go - round as it spins. choose...
a third grader hanging motionless from the monkey bars. choose...
a car driving on interstate 64. choose...
a fourth grader sitting at the top of a slide. choose...
check

Explanation:

Step1: Recall Energy Types

Potential Energy (PE) is stored energy (e.g., due to position/height). Kinetic Energy (KE) is energy of motion (when an object moves).

Step2: Analyze Each Situation

• Trophy on shelf: Stored (height) → PE
• Football player running: Moving → KE
• Second grader cartwheeling: Moving → KE
• Merry - go - round spinning: Moving (rotational) → KE
• Third grader hanging motionless: Stored (height, no motion) → PE
• Car driving: Moving → KE
• Fourth grader at top of slide: Stored (height, no motion yet) → PE

Answer:

1. A trophy sitting on shelf in the display case: Potential Energy
2. A football player running with the ball: Kinetic Energy
3. A second grader doing a cartwheel: Kinetic Energy
4. A merry - go - round as it spins: Kinetic Energy
5. A third grader hanging motionless from the monkey bars: Potential Energy
6. A car driving on Interstate 64: Kinetic Energy
7. A fourth grader sitting at the top of a slide: Potential Energy
