No. The average speed is the average of the magnitude of the velocity but not the magnitude of the average of the velocity.

This is because for vectors |A + B| ≤ |A| + |B|.

Suppose you travel 100 metres due East at 10 metres per second and then 100 metres due North also at 10 metres per second. Your speed, throughout, is 10 metres per second and so that is your average speed.

But your average velocity is the total displacement vector divided by the total time. This is

100*sqrt(2) metres due NE/20 sec = 7.07 metres per second due North East.

Its magnitude is 7.07 metres/sec.

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.

Velocity is a vector, and so it has two components -- magnitude (speed) and direction. Speed is a scalar, and it is the magnitude of velocity, a vector.

The definition of speed is the size/magnitude/measure of an object's velocity. Average speed = distance divided by time

No. Speed is the magnitude of velocity and acceleration is the change of velocity in time.

No. Average speed is.

The magnitude of both can be the same.

The magnitude is the speed, such as m/s or km/h.

No, velocity is a vector quantity (i.e. magnitude & direction) while speed is a scalar quantity (i.e. magnitude only).

Speed is equal to the magnitude of velocity when the object is moving in a straight line without changing direction. In other words, if the velocity vector is pointing in the same direction as the motion of the object, then the speed will be equal to the magnitude of the velocity.

no its a vector quantity,not a scalar quantity,bcz still it z a velocity bt NT a speed On a typical journey the average velocity is the straight-line distance between the start and finish, divided by the time taken, and it also has a direction. The average speed is the actual distance run, divided by the speed. The average speed might not be equal to the magnitude of the average velocity. For example on a round trip the average speed might be 40 mph, while the average velocity is zero.

Velocity has magnitude and direction and speed only has magnitude.

what is magnitude of average velocity

speed has magnitude. velocity has magnitude and direction.

Velocity is a vector, and so it has two components -- magnitude (speed) and direction. Speed is a scalar, and it is the magnitude of velocity, a vector.

Speed and velocity always have the same magnitude, becausespeed is the magnitude of velocity.The difference is that velocity has a direction but speed doesn't
