F=ma
mass of object = 20kg
acceleration due to gravity = 9.81m/s^2
F=20*9.81
F=196.2 kgm/s^2 or 196.2 N
weight
The force of gravity between the Earth and an object on its surface is what we call the object's "weight". What is not generally appreciated is that the object attracts the Earth toward it with the same force. This means that whatever your weight is on Earth, it's the same as the Earth's weight on you.
weight, The weight of an object is the force of gravity acting on it.
The force of gravity pulls it down to the earth.
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.
That's usually called the object's "weight". Like say if you're talking about the forces of gravity between you and the Earth, the force of gravity acting on you is your weight on the Earth, and the force of gravity acting on the Earth is the Earth's weight on you, and they're equal.

Weight is the measurement of gravitational force on an object, relevant to Earth.
On earth, the forces acting on any object is gravity. Since there is an equal and opposite reaction to any force, the earth pushes back on the object. This is called the normal force.
The scientific definition of weight is that it is the the force of gravity acting on an object.
In that case, the object is said to be in "free fall". If the gravity is due to the attraction from a single object, such as Earth, the other object will accelerate towards Earth or whatever.
The force of gravity on an object is called its weight.Note that mass is what CAUSES this force of gravity.
The downward force acting on an object in free fall is Gravity.
