Given:
A boy walks up the hill. His displacement from his starting point is (800,150)meter.
To find:
Gravitational potential energy gained ?
Calculation:
First of all, it's important to know a few things about gravitational potential energy !
- Gravitational Potential Energy is not path dependent, so it only depends on the final position w.r.t the reference plane.
Here, we need to consider only the Y axis value for calculation .
So, the potential energy gained is 1500m joule.

P.E.= mgh
⇒P.E.= m×10×150
⇒P.E.= 1500m joule
So, the potential energy gained is 1500m joule.
