Speed is a measure of distance traveled over a certain amount of time, while velocity measures displacement over time, as opposed to distance. ... The rate of change for velocity is acceleration, which is measured in displacement over time over time (e.g., m / s^2).

Because acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is also a vector quantity. Acceleration is defined as the change in the velocity vector in a time interval, divided by the time interval.

Speed is the distance covered in a unit of time while acceleration is the rate of change of speed. The unit of speed in the metric system is meters per second (m/s) while that of acceleration is meters per second squared (m/s2). Speed is a scalar quantity while acceleration is a vector quantity.

acceleration is defined as the rate of change of velocity, or, equivalently, as the second derivative of position. ... derivative is a measurement of how a function changes when the values of its inputs change. ..... velocity is defined as the rate of change of position.

Velocity is speed with a direction, so distance over time with a specific direction. And acceleration, the king of them all, is distance over time squared, aka the rate at which velocity changes. Whether you are speeding up, slowing down, or changing directions, you are changing your velocity and thus, accelerating.

The velocity of an object is found by taking the derivative of the position function: . Velocity can be thought of as the object's speed and direction, or change in position over time. The acceleration of an object is equal to the derivative of its velocity and describes the object's change in velocity over time.

The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.

Speed requires distance. Velocity requires direction. Speed is the result of a change in direction. Velocity is the result of a change in acceleration.

Average speed is distance divided by time. Velocity is speed in a given direction. Acceleration is change in velocity divided by time.

Speed and velocity are measured in units of distance per time. Acceleration is the change in velocity (or speed) per time interval. Acceleration units are speed per time.

The relation between velocity and time is a simple one during uniformly accelerated, straight-line motion. The longer the acceleration, the greater the change in velocity. Change in velocity is directly proportional to time when acceleration is constant.

Velocity is vector: That means that going in one direction in velocity is not the same as going in the opposite direction. ... Acceleration is rate of change of Velocity: How quickly your velocity is increasing or decreasing. It is measured in meters per second per second, or m/s/s.

Speed, being a scalar quantity, is the rate at which an object covers distance. ... On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

Speed is a scalar quantity which specifies the rate at which distance is changing but does not specify in which direction. Velocity is a vector quantity which specifies both speed and direction. So speed is the magnitude of velocity (the length of the vector).

Acceleration is defined as the rate of change of an object's velocity. Just like the derivative of the position function gives you the velocity as a function of time, the derivative of the velocity function (which is also the second derivative of the position function) gives you the acceleration as a function of time.

The short answer is that velocity is the speed with a direction, while speed does not have a direction. Speed is a scalar quantity -- it is the magnitude of the velocity. Speed is measured in units of distance divided by time, e.g. miles per hour, feet per second, meters per second, etc....

When velocity is changing, the word acceleration is used. Acceleration is also a vector. You speed up if the acceleration and velocity point in the same direction. You slow down (also referred to as decelerating) if the acceleration and velocity point in opposite directions.
