Pitch is a rotating movement of the body of the aircraft about the axis of the wings. Pitch is represented by rotating to tilt the aircraft up or down.
Yaw is a rotation left and right, similar to turning your head to the left and right.
Roll is a rotation of the aircraft about the front to rear axis. An aircraft would roll if the pilot wanted to turn it to fly upside down.
It is a tool used to manualy change the pitch of an variable pitch aircraft propeller.

Pitch controls the angle up or down of the aircraft.
The pitch of the aircraft is the amount of rotation along the lateral axis. The lateral axis runs along the wingspan, therefore the pitch is the amount that the nose of the plane is above or below that axis.
Elevators control the pitch (up and down) of the aircraft. Ailerons control the roll of the aircraft. And rudders control the yaw of the aircraft.
That would be the RPM gauge. On an aircraft with variable pitch prop it would be the manifold pressure gauge.
It is simply the rate at which the aircraft can pitch - ie. rotate around the lateral axis, which is roughly the wings. The faster an aircraft can pitch, the greater the "g" limit required, and achieved. Otherwise it would become overstressed. Most aircraft can exceed their 'G' Limits, but pilots prevent this through "seat of the pants" indications of wing loading.
there are a couple of ways to slow a plane down. the first is to throttle down, this will help decrease speed. the second is pitch, if you increase the pitch, or raise the nose, you can decrease speed too. most aircraft have a pitch control wheel that raises or lowers the pitch (Nose) of the aircraft. By raising the pitch alittle and throttling down, you will slow the aircraft down really quick.
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch
Elevators change the pitch of the aircraft.
Elevators help your takeoff by raising the tail of the aircraft and putting the whole aircraft in 'flight' attitude.
