What is the potential energy of a 2-kg vase sitting on a table with a height of 1<br> meter?

lisov135 [29]

"20 J" is the "Potential Energy" of "vase" on the table.

<u>Explanation</u>:

The body possess some energy according to the position of the object that is the when an object is placed at a height it stores some energy it is called "Potential Energy".

Formula used to calculate the "Potential Energy" is $m\times g \times h$

Where, "m" is mass of vase is given that 2 kg, "g" is acceleration due to gravity is $10 m/s^2$ and "h" is height of the object where it placed is 1 m.

Substitute the given values in the formula,

Potential energy of the vase = $2\times10\times1$

Potential energy of the vase = 20 J
