Hey mate!

Thank you for asking this question! ❤

Answer:

___________________________________________________

The gravitational potential energy of an object can be both positive as well as negative...

There is no myth stating that gravitational potential energy is always positive...

The value of g does not mean that mgh will always be positive...

g is the value the acceleration of an object due to the gravity of a planet, which in many instances, can be negative as well...

It is taken as positive, as a body falling downwards will have a positive acceleration...
