No. Gravity is a constant and not a force. The force due to gravity does increase as your body mass increases though.
Yes, the force due to gravity (
Explanation:
Newton's universal law of gravitation is:
Where
The force of gravity between two objects does depend on mass (more mass, more force), and the distance (bigger distance, less force).
Let's consider the special case where you are on the surface of the earth (or very close to the surface). We can plug in the mass and radius of the earth:
You will notice that
Which looks a lot like Newton's second law:
This is just a long-winded way of saying
The force due to gravity is not a constant.
