Relative gravitational potential energy.
Gravitational potential energy = (weight of the object) x (height) or Potential energy = (mass) x (acceleration of gravity) x (height)
Gravitational potential energy describes how much energy a body has in store by virtue of having been elevated to a specific height. The formula to calculate gravitational potential energy is:.U = mgh.Where:U is the potential energym is the mass of the objectg is the acceleration due to gravity, andh is the height the object will fall if dropped.
Just look at the formula, the factors are all there. GPE = mgh (mass x gravity x height)
For gravitational potential energy: PE = weight x height PE = mgh (that is, mass x gravity x height) The first formula is appropriate in this case, since you already know the weight.
The gravitational potential energy is equal to: GPE = mass x gravity x height Or equivalently: GPE = weight x height
Height & weight.
The formula for potential energy is: G.P.E. (gravitational potential energy) = Weight x Height
Multiply its weight by its height.
Gravitational potential energy = (weight of the object) x (height) or Potential energy = (mass) x (acceleration of gravity) x (height)
potential energy = mass x acceleration due to gravity (9.81m/s2) x height
It can easily be derived from the formula for work: force x distance. The force in this case is the weight, and the weight is mass x gravity (mg). The distance, of course, is the height.

weight times height
When an object is lifted to a certain height, the mechanical energy of the person or system lifting the object gets transferred into the potential energy of the object. Thus if an object of mass/weight 'm' is lifted to a height 'h', then the potential energy possed by the object at height 'h' is given as: Potential Energy (P.E)= m*g*h, where g is acceleration due to gravity and whose value is 9.8 m/s2.
When a rock is held at a height above ground it has gravitational potential energy because if it is released it will be pulled down by gravity and aquire energy due to its motion. Quantitatively; it is the work required to move a weight from height 0 to height y and has the formula PE = mgy . where mg is the weight of an ogject of mass m. This formula is only valid near the earth's surface where the objects weight doesn't change in the distance y. If y is far from the surface then the object's weight changes (because g, the acceleration due to gravity, changes) and in order to get the correct formula you have to use calculus. But I assume that's not where you're at.
One's weight in newtons is the size of the force of gravity acting upon one's centre of mass. That is your weight in kg times the gravitational constant (10 or 9.81 based on which course you take). To get your weight in kg, you have to multipy your weight in lbs by .4536 The formula of getting potential energy is m*g*h, where m is the object's weight in kg, g is the gravitational constant (9.81 m/s2), and h is the height of the hill, if the potential energy is given in Joules (kg*m2/s2). To get the height of the hill, you have to divide potential energy by mass times gravitational constant, so the formula is Epot/(m*g) = h, where Epot is the potential energy.
According to one website I visited, the formula is:PE (subscript, gravitational) = weight x height = mphThe website where I found this has calculator tools and the formulas.
