There are typically four forces described in physics:
Gravity
Electromagnetic
Weak
Strong
Sometimes the electromagetic and weak forces are referred to as "electroweak"
I'd like to elaborate on this actually. If you consider the macroscopic scale there are also other consolidated forces engineers take into account to simplify problems such as drag forces, damping forces and etc.
The main force acting on a falling book, besides gravity, is air resistance or air drag. As the book moves through the air, the air molecules exert a force in the opposite direction of motion, which opposes the book's downward movement. The magnitude of this force depends on factors such as the speed and size of the falling object.
The force of gravity is called weight. It is the force exerted on an object due to gravity pulling it towards the center of the Earth.
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 on the moon is about one-sixth (1/6) of the force of gravity on Earth.
The terms "gravitational force" and "force of gravity" are interchangeable and both refer to the same force exerted on objects due to gravity. When an apple is falling, the force of gravity (gravitational force) is indeed acting on it, causing it to accelerate towards the Earth.
There is gravity everywhere in Creation. It causes a force between every two bits of mass in the universe.
well if you think about it free fall is just an object that falls down with no force besides gravity pushing on it. and projectile is also something or an object that has no force acting on it besides gravity. so there pretty alike. that is how they compare.

A spring balance using a known mass will enable you to measure the force due to gravity [or acceleration].
what is the force of gravity on mecury
Gravity is a force but has no mass.
gravity not as a force, but as the curvature of spacetime
None. Gravity IS the force in this case.
gravity is a force by which objects are attracted to the centre of.
Gravity Force was created in 1989.
