Question

A chair is powered by an electric motor so what useful energy transformations take place.

Like is it electrical energy into kinetic energy into gravatational potential energy

OR

Like is it electrical energy into gravatational potential energy into kinetic energy

And please say which one it is or if they are BOTH wrong then please tell me the correct transformations that occur

Answer 1

Hi,

Are you talking about a chair lift (like on stairs)?

If so,

It is electrical --> kinetic ---> gravitational

Because it has to move, to be able to gain gravitational potential energy.

Hope this helps ;)

Answer 2

It's electrical energy into kinetic energy

there is no connection to gravitattional potential energy as that comes into the picture only when an object is moved UP or DOWN ,not sideways.

Answer 3

either could be correct, it depends on what this electrified chair is doing.

As usual, you did not provide enough information.

Answer 4

its electrical to gravatational to kinetic :]

Answer 5

well what is the chair doing, you havent said. is the chair moving? Is it moving upwards? is it heating up?
