How is speed velocity and acceleration related?

In: Physics [Edit categories]

Answer:

Speed is the rate of motion usually expressed as distance traveled per unit of time.

Velocity is the rate of change of position. Both speed and direction are required.

Acceleration is the rate of change in velocity. In common speech, acceleration is only for an increase in speed; a decrease in speed is deceleration. In physics, any increase or decrease in speed or change of direction is referred to as acceleration.

How are speed velocity and acceleration related?
Speed is a scalar value meaning it has only a magnitude and velocity is a vector value meaning it has magnitude and a direction. The magnitude could be speed but if you say, "I'm going 3 meters per...
How is acceleration related to speed and velocity?
Velocity is the combination of speed and its direction. Any change of speed, or direction, or both, is acceleration.
How are mass force speed velocity and acceleration related?
Force is related to acceleration because F= mass X acceleration. Velocity is speed with a direction included. For example, 35 mph is a speed, but 35mph north is a velocity. Acceleration is the rate...
