When an object is moving along a straight line at a variable speed, we can express the magnitude of the rate of motion in terms of average velocity.It is the same way as we calculate average speed.

It's not. Unless you add a direction to speed it will not become velocity. Since positive and negative are sometimes used to denote direction, absolute value of velocity may equal speed (certain situations)

Distance = time * average speed (velocity) Average speed = Distance/time

The average velocity in a particular direction = distance travelled in that direction / time taken. Velocity is a vector so the direction is important. If I go from A to B and then return to A my average velocity will be zero. My speed, on the other hand, will not be zero.

yes, the average speed equals distance divided by time

No, the numerical ratio of average velocity to average speed is not always equal. Average velocity is a vector quantity that includes both magnitude and direction, while average speed is a scalar quantity that only considers magnitude. The ratio will be equal only when the object moves in a straight line.

When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.

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.

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.

The instantaneous velocity is equal to the average velocity when the object is moving at a constant speed in a straight line.

Average speed is the distance traveled divided by the time taken, and it is a scalar quantity. Average velocity is the displacement divided by the time taken, and it is a vector quantity that includes direction. Average speed and average velocity are only equal when an object moves in a straight line, but when there are changes in direction, they can be different.

As long as there is no change in direction then they are effectively the same.

Yes, instantaneous speed can be equal to the magnitude of the average velocity when an object is moving in a straight line without changing its direction during the motion. This occurs at the moment when the instantaneous velocity vector is in the same direction as the average velocity vector.

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 speed and its direction. Average velocity is average speed and its direction.

The average velocity of an object is equal to its instantaneous velocity in uniform motion. Uniform motion occurs when an object moves at a constant speed in a straight line, resulting in a constant velocity throughout the motion.

An object's average velocity is equal to its instantaneous velocity when the object is moving at a constant speed in a straight line. This means that the object covers equal distances in equal intervals of time, resulting in the average velocity over a period of time being equal to the instantaneous velocity at any given moment within that period.
