If you are referring to "rate of travel", the most common alternative would be "velocity". You could also use "kph" and "mph", meaning kilometers per hour and miles per hour.
If you are referring to the street drug, methamphetamine, words such as "meth", "crystal" and "crank" were once popular. Today it is mostly referred to as "crystal meth".
The adjective for the noun speed is speedy.
The verb "to speed" has the participles speeding and sped. Only speeding could be used as an adjective (e.g. speeding cars, speeding bullet).
speed. Velocity is another word for determining speed
Speedy is a word that describes fast action. Some synonyms for "speedy" would be quick, fast, hurried, rushed, and accelerated.
Rapid,Haste,Retentive,
flash
Haste
Zero velocity = No acceleration
Alteration, variation? (: Delta (Greek letter - triangle) stands for change. eg. Change in velocity = delta Velocity. Change in time = delta t.
The root word for velocity is veloc. Meaning...I do believe..speed.
We will reach terminal velocity just before we hit the ground, then the result of our velocity will be terminal.
Technically, it is acceleration either way. If something is slowing down, the acceleration is negative. Slow down or Decrease velocity
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).
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.
velocity = la velocidad
Velocity is hastighet in Swedish.
