Answer:
A. Sound comes from the ball every time it bounces.
B. The ball is warmer after it stops bouncing than it was before it
started bouncing
Explanation:
It is evidently shown that the ball shown energy transformation because it produces sound at each bounce and also becomes warmer after the bounce.
The law of conservation of energy suggests that energy is neither created nor destroyed but transformed from one form to another.
- a bouncing ball produces sound energy at each bounce. This is conversion of potential energy initially of the ball into kinetic energy of sound.
- Also, the motion of the ball produces kinetic energy which causes the ball to warm up, this is thermal energy.
- We see that a ball originally with potential energy has yielded the kinetic forms of energy which are sound and thermal energy.
Explanation:
Scientists collect data for decades after Apollo 11's return to earth. Finding include that the moon is moving farther away from earth and that the universal force of gravity is stable.
