Acceleration is the rate of change of the velocity (speed) of an object. Acceleration is the derivative of the speed vs. time function.
Speed
no, speed is a scalar quantity. forces is a vector quantity that measures the strength and states the direction. speed tells you how fast an object moves in specific instant. :)
Velocity
It is a satellite.

Its speed.
Not quite. Speed only measures how fast an object is moving, while velocity measures change in position relative to time. For example, an object that moves from point A to point B, and then back to it's original position, may move with speed, but since there is no change in position, velocity would be 0.
Motion of something determined by its mass and velocity
Stantaneous speed is how fast an object moves at any given time.
miles/kilometers per second/minute/hour
No, distance and speed are two separate measurements. Distance is how far an object moves relative to speed and time, and speed is how fast an object moves relative to time and distance.
