Potential energy
When you lift an object, you are transferring energy in the form of work done against gravity. This added energy gives the object potential energy, which is stored energy due to its position relative to the earth's surface.
The object's kinetic energy can't be determined from the given information. Kinetic energy = (1/2) (mass) (speed)2 The question gives the object's mass, but we need its speed too.
It is the sum of potential and kinetic energy.
An object sitting on the ground at sea level has gravitational potential energy due to its position relative to the Earth's surface. This potential energy is determined by the height of the object above the ground and its mass, which gives it the potential to be transformed into kinetic energy if the object falls.
With potential energy, what matters is the difference in potential energy, not the energy in absolute terms. To simplify calculations, the gravitational potential at infinity is arbitrarily set to zero. This gives objects that are nearer than infinity (to any object that attracts them gravitationally), a negative potential energy.With potential energy, what matters is the difference in potential energy, not the energy in absolute terms.

The qualitative relationship between force and potential energy is that potential energy is associated with the position of an object within a force field. As an object moves against or with a force field, its potential energy changes accordingly. The force acting on an object is related to the change in potential energy through the gradient of the potential energy function.
Gravitational potential energy is the energy stored in an object due to its position in a gravitational field. The higher the object is positioned in the gravitational field, the greater its gravitational potential energy. This energy can be released when the object falls or moves to a lower position in the field.
Potential energy is the energy that an object possesses due to its position in a force field or interaction with other objects. It is dependent on the object's position or configuration within the system. This energy can be released or converted into other forms of energy depending on the interactions involved.
Mechanical energy is formed through the combination of potential energy (stored energy) and kinetic energy (energy due to motion). When an object moves, its kinetic energy increases, and when it is lifted against gravity, its potential energy increases. The sum of these two forms of energy gives the object its mechanical energy.
Objects at higher elevations have more potential energy because they have the potential to fall to lower elevations due to gravity. The higher an object is, the more gravitational potential energy it has because gravity has more "pull" on it. This potential energy can be converted to kinetic energy as the object falls.
