Question

a student drops a basketball from shoulder height. it bounces several times but never reaches the original height. which statement best explains what is happening?
energy is lost forever
kinetic energy is destroyed after each bounce.
some kinetic energy is transformed into other forms.
the law of conservation of energy does not apply.

Explanation:

According to the law of conservation of energy, energy is neither created nor destroyed but can change forms. When a basketball bounces and doesn't reach its original height, some of its kinetic energy is transformed into other forms like heat and sound energy during the impact with the ground. Energy is not lost forever and kinetic energy isn't destroyed but rather converted. The law of conservation of energy always applies.

Answer:

Some kinetic energy is transformed into other forms.
