Question

(a) What is the average velocity when the velocity of an object changes at a uniform rate? Write its Sl unit.
(b) State the condition under which the magnitude of average speed and average velocity of an object are equal.​

Answer 1

Answer:

Average velocity (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two. Where: ¯v = average velocity. v = final velocity.

Average velocity would be equal to average speed when the total distance travelled equals the net displacement of a particle. This happens when a particle moves along a straight line in a fixed direction.

Answer 2

Answer:

1.The average velocity of an object is its total displacement divided by the total time taken. In other words, it is the rate at which an object changes its position from one place to another. Average velocity is a vector quantity. The SI unit is meters per second. However, any distance unit per any ti

me unit can be used when necessary, such as miles per hour (mph) or kilometer per hour (kmph).
