Question

under what condition is the average speed equal to the average velocity​

Answer 1

$\large{\underline{\underline{\pmb{\sf{\color{yellow}{Answer:}}}}}}$

The magnitude of the average velocity of an object is equal to its average speed, only in one condition when an object is moving in a straight line. The average speed is the total distance travelled in a given time frame and velocity is the total displacement in the time frame. The magnitude of average velocity and average speed will be the same when the total distance travelled is equal to the displacement.

The average velocity of a body in a certain time interval is given as the displacement of the body in that time interval divided by time.

☛The average velocity is the ratio of total displacement and time.The.average speed is the ratio of total distance and time.

The average velocity is the ratio of total displacement and time.The.average speed is the ratio of total distance and time.Therefore the average speed and average velocity are equal if the total displacement is equal to the total distance that is if the body travels along a straight line without changing the direction.
