A boy throws a yo-yo downward and watches it climb back up. As the yo-yo is going down, which types of energy are changing? Translational kinetic energy Rotational kinetic energy Gravitational potential energy

A boy throws a yo-yo downward and watches it climb back up. As the yo-yo is going down it changes from potential to kinetic in rotational forms.Rotational kinetic energy is used in the Yo-Yo.

Explanation:

When a boy throws a yo-yo downward its string for a distance h, loses its potential energy in amount and gains kinetic energy in both translational and rotational forms. As it climbs back it loses its kinetic energy and retrieves its potential energy.In a modern Yo-Yo, the string is not tied to an axle, but loops around it. When Yo-Yo hits the bottom area of its string, a movement of an upward action of force on the axle from the string will stop the descent. Then Yo-Yo spins axle only with rotational kinetic energy.

Global warming was a major concern some people do not care global warming is fake it is not real the percentage of it happening  is slight
