Question

what is speed? what is average speed​

Answer 1

Answer:

Speed can be thought of as the rate at which an object covers distance. ... Speed has the dimensions of distance divided by time

Average speed is calculated by dividing the total distance that something has traveled by the total amount of time it took it to travel that distance. ... Average speed is usually applied to vehicles like cars, trains, and airplanes. It is often measured in miles per hour (mph) or kilometers per hour (kph).

1) The rate of change of position of an object in any direction.

Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.

$\pink\longmapsto~\bf\orange{Speed~=~\dfrac{Distance}{Time}~}$

$\pink\longmapsto~\bf\green{S.I~unit~of~Speed~\longrightarrow~m.s^{-1}~}$

$\pink\longmapsto~\bf\gray{Dimensional~formula~of~Speed~is~[M^0\:L^1\:T^{-1}]~}$

2) The average speed is the total distance traveled by the object in a particular time interval.

The average speed is a scalar quantity. It is represented by the magnitude and does not have direction.

Formula of Average Speed

The formula for average speed is found by calculating the ratio of the total distance traveled by the body to the time taken to cover that distance.

$\pink\longmapsto~\bf\red{Average\:Speed~=~\dfrac{Total\:Distance}{Total\:Time\: taken}~}$
