The gravitational potential energy of an object is always measured relative to the

The gravitational potential energy of an object Is always measured relative to the height of the object. It has the equation equal to mass PE = mgh where PE is the potential energy, m is the mass of the object, H is the height of the object and g is the acceleration due to gravity. 

The gravitational potential of an object is always measured relative to reference level/another point

Energy is the ability to do work. Energy can change from one energy to another

Gravitational potential energy is the energy that an object has because of its position

The potential energy can be formulated:

Ep = m. g. h

E = potential energy of an object, joule

m = object mass, kg

g = gravity acceleration, m / s2

h = height of an object, m

The higher the object from the surface of the earth and the greater the mass, the greater the potential energy of the object. Earth's gravity also affects the potential energy of objects

Potential energy itself includes mechanical energy

Em = Ek + Ep

Em = mechanical energy

Ek = kinetic energy

Ep = potential energy

The amount of kinetic energy and potential energy of objects is always constant

hèllo, sorry i really need some more points so if you need this qustion answered than retype it

that would be because of both gravity and friction. so     c
