Is numerical ratio of average velocity to average speed always equal?

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.


Can the average speed ever equal the instantaneous speed?

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.


When is the average velocity is equal to the instantaneous velocity?

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.


When is speed equal to the magnitude of velocity?

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.


When is the instantaneous velocity equal to avg velocity?

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


When is average speed of an object not equal to average velocity?

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.


Is there a circumstance average speed equal to average velocity?

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


Does the instantaneous speed ever equal the magnitude of its average velocity?

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.


Does average velocity and average speed have the same number?

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.


How is velocity different from average speeed?

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


In which type of motion is the average velocity of an object equal to its instantaneous velocity?

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.


When is an object's average velocity equal to its instantaneous velocity?

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.
