# How average speed and average velocity are related to each other?

Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger.

For the instantaneous value of average velocity, average speed and average velocity are equal.

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.

Both are velocity functions. Instantaneous velocity is the derivative of the average velocity * * * * * They are both speed functions. Velocity is a vector related to speed but quite irrelevant in this context. An object rotating at a constant [angular] speed has a velocity that is continuously changing but that has no relevance.

BecuZ average is the same limit and the other is nesting velocity

The definition of velocity is the speed of something in a given direction. Therefore it's related to speed.

The magnitude of average velocity of an object equal to its average speed if that object is moving with CONSTANT velocity.

yes, velocity is speed with direction; average speed has no direction, bit average velocity does

That is the case when you are talking about instantaneous speed and velocity - or when the velocity is constant. In the case of an average speed and velocity, this relation does not hold.

the instantaneous velocity or speed is the speed a body travels at a particular and average velocity is the total distance an object

Because velocity is a measurement of change of speed rather than an average constant speed. To get the average speed (as you rightly said) - you divide the total distance travelled by the time taken. The average velocity is the change in speed over time (either an increase or decrease).

Yes - just like any velocity, average velocity is a vector and has a direction associated with it. Speed, on the other hand is only an intensive property which has no specific direction associated with it. You could consider speed to be the magnitude of the velocity vector.

An object moving in a circular path at constant speed will have a non-zero average speed and zero average velocity since velocity is a vector parameter,

Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.

Speed is a scalar, velocity is a vector. In other words, when a direction is important, you talk about velocity.Speed is a scalar, velocity is a vector. In other words, when a direction is important, you talk about velocity.Speed is a scalar, velocity is a vector. In other words, when a direction is important, you talk about velocity.Speed is a scalar, velocity is a vector. In other words, when a direction is important, you talk about velocity.

Momentum is calculated by Mass * Velocity (Speed is the magnitude of Velocity). If velocity increases and mass remains constant, Momentum (measured in kg m/s) increases and if velocity decreases, momentum decreases.

If the car has an average speed of 65 mph, when it returns to its starting point, it will have a displacement of zero and an average velocity of zero, because velocity has both speed and direction.

Since speed is a scalar quantity, the only way the average speed can be zero is if the instantaneous speed is at all times zero, making it not a moving body, so no on the average speed. The average velocity, on the other hand, can easily be zero. The simplest example is you running in a circle.

No. Average velocity is still a velocity.Distance is a product of (a velocity or speed) times (a length of time).

For example, an object goes in a circle, at a speed of 50 km/hour. The average speed is 50 km/hour; the average velocity is zero.

If an object is in motion it has a Velocity, which is speed and direction.

Velocity is the combination of speed and its direction.Any change of speed, or direction, or both, is acceleration.

Speed is a scalar, velocity is a vector. In other words, when the direction of the speed is relevant, it is called a velocity.

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
