mass and distance
You can look at it in different ways; the following explanations are actually quite related to one another:1) You need to apply force, against the force of gravity. 2) You are going to a place where you have a higher gravitational potential energy.

the force of gravity
The force of gravity between two objects is inversely proportional to the square of the distance between their centers. This means that as the distance between two objects increases, the force of gravity between them decreases.
Acceleration of gravity multiplied by mass gets you the weight of an object.The force of gravity on earth accelerates at 9.8m/s^2.Multiply the mass of the object (in Kg) by 9.8, and you will get the weight.Note:Mass of an object remains constant no matter where you are. Weight might not, because it is dependent on force of gravity.
The force of gravity at the surface of Uranus is approximately 8.69 m/s^2, which is about 0.886 times the gravity on Earth.
The force of gravity between 2 objects.
By Gravity we mean the energy of Gravity E= - mGM/r = -mu/r. Force is the first derivative of energy so the force of Gravity is dE/dr = mu/r^2. Force is the first derivative for all kinds of energy.
The force of gravity pulling on a mass depends on the mass of the object and the acceleration due to gravity. The force can be calculated using the formula: force = mass x gravity. On Earth, the acceleration due to gravity is approximately 9.81 m/s^2.
The force of gravity on an object is determined by its mass and the acceleration due to gravity. The formula to calculate this force is: force of gravity = mass of the object × acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.81 m/s^2.
Gravity is the force that attracts two masses together. Weight on Earth is the force of gravity acting upon an object on Earth. The formula for force is: F=ma -or- Force=mass x acceleration So, multiplying an object's mass by its acceleration due to gravity (9.8m/s2 on Earth) will give you the measurement of the force of gravity acting upon the object, also known as the object's weight.
