Question

What is the gravitational potential energy of a `12 kg` object on a shelf `3 m` high?

Answer 1

`352.8 \ "J"`

Explanation:

Gravitational potential energy is given by the equation,

`"GPE"=mgh`

• `m` is the mass of the object in kilograms

• `g` is the gravitational acceleration, which is approximately `9.8 \ "m/s"^2`

• `h` is the height of the object in meters

And so, we got:

`"GPE"=12 \ "kg"*9.8 \ "m/s"^2*3 \ "m"`

`=352.8 \ "J"`
