It decreases with height.
As height increases, the velocity generally decreases due to the effect of gravity. This is because potential energy increases while kinetic energy decreases, resulting in a slower velocity.
as we go up gravity decreases
If the force of gravity increases, weight will increase because weight is the measure of the force of gravity on an object. However, mass remains constant as it is a measure of the amount of matter in an object and does not change with gravity.

Gravitational potential energy is directly proportional to the height of an object above a reference point. As an object's height increases, its gravitational potential energy also increases because the object has the potential to do more work as it falls to a lower height due to gravity. Conversely, as the object's height decreases, its gravitational potential energy decreases.
Pressure decreases as height increases and vice-versa.
-- If the mass of Mars increases, then its surface gravity also increases. -- If the mass of Mars decreases, then its surface gravity also decreases. -- So long as its radius does not change, the acceleration due to gravity on or near the planet's surface is directly proportional to its mass.
The force of gravity increases with mass, meaning that objects with more mass have a stronger gravitational pull. However, the force of gravity decreases with distance, following an inverse square law. This means that as you move farther away from an object, the force of gravity weakens rapidly.
When a ball is dropped, its potential energy decreases due to the decrease in height, while its kinetic energy increases as it gains speed due to gravity pulling it downwards.
As the distance between two objects decreases (i.e. they get closer together), the force of gravity increases.
It decreases
It isn't. Gravity can be viewed as emanating from the centre of a body with mass. As the distance increases from the centre then the gravity decreases.
