Below is a clip from the lyrics, "Kinetic & Potential Energy" by Tom Glazer & Dottie Evans:
"The rolling boulder crashing down the mountain is kinetic energy. The boulder sitting up on the mountain, that's potential energy. You stretch a rubber band and hold it. The heat that comes when a fire is burning, that's kinetic energy". Which part of the song shows enegy as stored?
You stretch a rubber band and hold it.

25. Alicia conducted a science investigation using the following steps:
Take 200 grams of clay and roll it into a ball.
From 5 meters away, throw the clay ball against the wall.
Observe the clay ball stuck to the wall after throwing it.
Repeat steps 1-3.
The pictures above show the clay ball and how it looked after Throw 1 and Throw 2. Which statement best explains why the clay ball after Throw 1 and Throw 2 have different shapes?
A. For Throw 1, Alicia moved further away from the wall than 5 meters.
B. For Throw 1, Alicia stayed the same distance from the wall.
C. For Throw 1, Alicia threw with a greater force which increased the speed of the clay ball.
D. For Throw 1, Alicia threw with less force which decreased the speed of the clay ball.
C. For Throw 1, Alicia threw with a greater force which increased the speed of the clay ball.
