Gravitational force of attraction....
Speed, velocity.

Gravity
Indicated airspeed compared to ground speed are different due to the movement of air (winds) around the aircraft.
No. Speed and time are different things.
Gravity and air resistance will both play a part. Air resistance is likely to reduce speed and gravity will cause the bullet to be pulled towards the ground.
This is because different UTP wires can be used. Each of them will run at a different speed and can be used for different things. This allows you to have different things to go on at once.
Speed and force are quite different things.
Ground speed is the speed the aircraft has compared to the ground. This is usually different from air speed, which is the aircraft's speed compared to the surrounding air. Thus an aircraft with 400 kph air speed and 50 kph headwind has a ground speed of 350 kph. For fun: with light aircraft with very low stall speeds it's possible to fly backwards (compared to the ground) if they fly into a headwind that's stronger than their lowest stall speed. I.e. their ground speed is negative.
It can have different meanings. Some are: Grand Sport Ground Speed
The critical speed of a SAG mill is the speed in RPM's at which centrifugal force causes the material being ground to be held against the inside of the shell. This speed is only dependent on the diameter of the mill.
Take off speed is different for different aircrafts. There is no one speed for all aircraft. Usually depending on the load etc, take off speed would be the speed at which enough lift is generated to enable the aicraft to lift off the ground.
