Because of conditioning. I expect that you would soon notice it if the gravitational constant fell to zero and you were flung off into space! You do not notice atmospheric pressure for a similar reason.

I assume you mean, the gravitation between two everyday objects is usually unnoticeable. That's not the same as the "value of the gravitational CONSTANT" being unnoticeable.Just do the calculation for some everyday objects. Assume any reasonable value for mass and distance. For instance, you might calculate the attraction between two trucks, each of them 20 tonnes (20,000 kg), at a distance of 10 meters.
The gravitational attraction, in this case, is a really small number. For comparison: Please note that the formula gives you a force in newton. The weight (which is a force) of an object with a mass of 1 gram (e.g., 1 cc of water) is about 0.01 newton.
You need three things: m = mass of the object (in kilograms) g = gravitational acceleration constant (usually 9.8 m/s^2) h = height of the object, usually from the ground (in meters) The gravitational potential energy are these three values multiplied together: PE = m • g • h
constant velocity is when you maintain speed and direction, this usually is in a straight line, and constant speed means that your speed is always constant at all times.
No, usually they conserve for the home stretch.
The speed of light in vacuum, usually denoted by c, is a universal physical constant important in many areas of physics. Its value is 299,792,458 metres per second, a figure that is exact since the length of the metre is defined from this constant and the international standard for time.[1] In imperial units this speed is approximately 186,282 miles per second.
A term that has no variable part is usually called a constant.
