An object's mechanical energy is the sum of the potential and kinetic energy it possesses.
The equation to use here is Epotential=mgh.Using your given values, and assuming the acceleration due to gravity to be 9.81ms-2, the potential energy can be found to be 147 Joules.
When you lift an object, the energy transferred to the object is called gravitational potential energy.
PE = m x 9.8 x h:So, 5kg x 9.8 x 5m = 245 joules potential energy.
If you know the kinetic and potential energies that act on an object then you can calculate the mechanical energy of the object. States that in an isolated system the mechanic energy is constant.

No, that's gravitational potential energy, such as a book sitting on a table. Elastic potential energy is the required energy to stretch or compress a solid or liquid.

Mass speed
its mass and height
An object that is stationary and at the top of something has "potential energy". (If you're getting into equations, it's PE = mgh, where PE = potential energy, m = mass of the object, g = the force of gravity, and h = the height of the object.)
Potential Energy The object is not in movement.
PE = m x 9.8 x h:So, 5kg x 9.8 x 5m = 245 joules potential energy.

Kinetic energy is related to movement (a faster object has more kinetic energy); potential energy is related to position (higher up, objects have more potential energy).Examples:A leopard waiting in a tree, motionless, waiting to jump on you has potential energy.A leopard leaping on you has kinetic energy, or energy of movement.Kinetic energy is the energy that an object has when it is in motion. Potential energy is the energy that an object has when it is at rest. For example, a book sitting on a desk has maximum potential energy and zero kinetic energy. If the book falls off of the desk, then its kinetic energy increases and its potential energy decreases.
To calculate an object's gravitational potential energy, the following factors must be known: Mass of the object: The gravitational potential energy of an object depends on its mass. The greater the mass of the object, the greater the gravitational potential energy. Height or distance: The gravitational potential energy of an object also depends on its height or distance from the reference point. The greater the height or distance of the object from the reference point, the greater the gravitational potential energy. Acceleration due to gravity: The gravitational potential energy of an object also depends on the acceleration due to gravity at the location of the object. The acceleration due to gravity is a constant value on the surface of the Earth, approximately equal to 9.8 meters per second squared. The formula for gravitational potential energy is: PE = mgh Where PE is the gravitational potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height or distance of the object from the reference point.
