Question

Which is an example of the conversion of gravitational potential energy into kinetic energy? a sliding hockey puck an idling car a swimming fish a falling raindrop

Answer 1

A falling raindrop.

The reason why it's because mass of a raindrop is under influence of gravity pushing it down towards earth surface. When it hit the surface kinetic energy is released.

Answer 2

a falling raindrop

Step-by-step explanation:

Kinetic energy depends on the mass and the velocity of an object.

Potential energy depends on the mass of an object an how high it is.

A raindrop initially has potenial energy because of its high above the ground, when is falling it has a velocity, and having a velocity means it now has kinetic energy.

By falling, the raindrop exchange potential energy for kinetic energy, as it falls, its potential energy is lower since it is at a lower altitud.

And also when it falls it accelerates towards the ground wich makes it have grater velocity and by analogy greater kinetic energy.
