Velocity is a vector, meaning that it has a direction. When it is being expressed, the direction is given with it (e.g. 5m/s NW).
Speed is a scalar, not a vector, so it doesn't have a direction connected with it. Thus, when it is expressed, the direction variable is omitted (e.g. 5m/s).
Acceleration is a change in velocity or speed over time. It will be a vector when it is referring to a change in velocty (e.g. 10m/s2 SE), and it will be a scaler when it is referring to a change in speed (e.g. 10m/s2).

JudySpeed is the rate at which an object covers a distance, velocity is the speed of an object in a specific direction, and acceleration is the rate at which an object's velocity changes. Speed is a scalar quantity, velocity is a vector quantity, and acceleration is also a vector quantity.

How are velocity and acceleration different?
Velocity is the rate of change of position of an object with respect to time, while acceleration is the rate of change of velocity of an object with respect to time. Velocity describes how fast an object is moving and in which direction, while acceleration describes how quickly the velocity of an object is changing, either in speed or direction.
If two automobiles have the same acceleration do they have the same velocity?
Not necessarily. Velocity takes into account both speed and direction, whereas acceleration only looks at changes in speed. So two cars with the same acceleration could have different velocities if they are moving in different directions.
How is speed velocity and acceleration alike?
Speed, velocity, and acceleration are all related to an object's motion. Speed is the rate of motion in a specific direction, velocity is the rate of motion in a specific direction with consideration of the object's displacement, and acceleration is the rate at which velocity changes. They all involve the concept of how quickly an object is moving, but each one provides different information about the object's motion.
Is deceleration a form acceleration?
Acceleration and deceleration are both the rate at which velocity changes, Deceleration is a negative acceleration. In an equation the rate of deceleration is shown as a negative acceleration valueCentripetal acceleration is different and represents the rate of change of tangential velocity. There is no equivalent centripetal deceleration.
What is acceleration speed and velocity?
Acceleration is the rate of change of velocity over time. It measures how quickly an object's velocity is changing. Speed is the rate at which an object covers distance, whereas velocity includes both speed and direction.
