# Difference between average velocity and average speed?

012

Velocity is speed and the direction of the speed.

(30 miles per hour going north) and (30 miles per hour going south)

are both the same speed, but they're opposite velocities.

## Related Questions  the instantaneous velocity or speed is the speed a body travels at a particular and average velocity is the total distance an object  speed is a scalar quantity ie it has no directions...........whereas velocity is a vector quantity ie it has directions...................Also speed has distance n velocity has displacement Avg velocity is the speed you are going. Constant acceleration is the rate you increase your speed. = = The technical difference is that speed has no direction but velocity has one. velocity is speed with direction; velocity is a vector and speed is a scalar The difference between an object's speed and an object's velocity is that the object's speed is how fast it is going, and the object's velocity is how many units of speed the object has traveled. "Direction". The only difference between velocity and speed is that velocity is a vector while speed is a magnitude. Therefore, velocity has a direction, while speed does not. The main difference between speed and velocity involves direction. Velocity involves an object moving in a particular direction. Speed is what it is: speed. Velocity is speed in a given direction, a vector quantity. The main difference between speed and velocity involves direction. Speed is scalar quantity and velocity is a vector - velocity has both speed AND direction (You might say that velocity is speed with an attitude!) Velocity has a direction while speed doesn't. This is why we say that velocity is a vector quantity and speed a scalar quantity. http://wiki.answers.com/Q/The_difference_of_speed_and_velocity" The difference between speed and velocity is that speed is a scalar quantity(that have only magnitude) and velocity is a vector quantity(that have both magnitude and direction). Speed is just a number; velocity includes information about the direction. In physical terms, speed is a scalar, whereas velocity is a vector. Speed is just a magnitude (or number); velocity includes information about the direction as well. In physical terms, speed is a scalar, whereas velocity is a vector. Speed is a scalar and velocity is a vector (has a direction). Speed can be said to be omni-directional like the speed of light. Velocity includes direction. And it's the 'difference', not the 'distance'.  For the instantaneous value of average velocity, average speed and average velocity are equal. If you know average speed then you cannot determine the acceleration: the very nature of being a average hides all the increases and decreases in speed which are the accelerations (technically, acceleration is change of speed in a direction). All average speed tells you is the constant speed at which you require to travel to cover the given distance in the given time; as the speed is constant, the acceleration is zero. Velocity is speed and its direction. Average velocity is average speed and its direction. velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same. ###### PhysicsScienceUnits of MeasureMath and Arithmetic Copyright © 2020 Multiply Media, LLC. All Rights Reserved.
