question 9 of 25
you throw a ball straight up into the air. what kinds of energy are changing as
it goes up?
a. gravitational potential energy and kinetic energy
b. kinetic energy and elastic energy
c. nuclear energy and sound energy
d. light energy and gravitational potential energy

Explanation:

When a ball is thrown straight up, it has kinetic energy (due to its motion) initially. As it rises, its height increases, so gravitational potential energy (which depends on height in a gravitational field) increases. At the same time, its speed decreases, so kinetic energy decreases. There is no elastic deformation (so no elastic energy), no nuclear reactions (so no nuclear energy), and no significant light - related energy changes (so no light energy in this context).

Answer:

A. Gravitational potential energy and kinetic energy
