An 5kg object is 6 meters what is the potential energy
AVprozaik [17]

Potential Energy of an object of 5kg which is 6 meters in height is 294 Joules.

Step-by-step explanation:

We are given:

Mass = m = 5 kg

Height = h= 6 meters

Potential Energy = ?

The formula used to find Potential Energy is:

Potential\,\,Energy =mgh

where m is mass, g is gravitational field and h is height

Putting the given values of mass and height, and g=9.8 m/s^2

Potential Energy = 5*9.8*6\\Potential Energy = 294 Joules

So, Potential Energy of an object of 5kg which is 6 meters in height is 294 Joules.

Keywords: Potential Energy
