The word speed is distance per unit of time. It is frequently used as a substitute for velocity, and it is in more common usage. But there is a difference between speed and velocity. Velocity has a direction vector associated with it. It's speed + direction. That's usually not a big deal when talking about "regular" stuff, but don't tell a physics teacher that.
an increase in speed - velocity is another word for speed
Relative vector of velocity. "Bearing" is another possibility.
Another definition for the word "acceleration" is "the rate of change of velocity per unit of time."
Still another velocity vector (or a zero vector).
Velocity does not indicate the length of time it takes for something to get from one place to another. Velocity measures the rate of change of the displacement.
Zero velocity = No acceleration
an increase in speed - velocity is another word for speed
Velocity A Vector is the measurement of velocity and direction.
Velocity
Velocity.
swiftness, hurry, velocity, pace, acceleration.
Relative vector of velocity. "Bearing" is another possibility.
Another definition for the word "acceleration" is "the rate of change of velocity per unit of time."
Still another velocity vector (or a zero vector).
velocity = la velocidad
Velocity is hastighet in Swedish.
Alteration, variation? (: Delta (Greek letter - triangle) stands for change. eg. Change in velocity = delta Velocity. Change in time = delta t.
