Question

what is speed and it's types​

Answer 1

Answer:

Speed

Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a given amount of time, while a slow-moving object covers a relatively small amount of distance in the same amount of time.

Common symbols v

SI unit m/s, m s−1

Answer 2

Answer:

$\huge\bf{\underline{speed}}$

✒ Distance travelled by the particle in unit time interval is known as speed.

or

✒ The rate of change of any respect with respect to time.

✏ speed = Distance / time

UNIT ➡ m/s OR cm/s

DIMENSION ➡ M° L¹

✡ it is scalar quantity

✡ it never can be negative

✡ it may increase,decrease or remains constant with respect to time.

$\huge\bf\underline{types \: of \: speed}$

1.Uniform speed:-

If particle travels equal distance in equal interval of time than the speed is known as uniform speed.

2.Non - Uniform speed:-

If particle travels unequal distances in equal time interval than, the speed is known as non- uniform speed.

3.Average speed:-

The ratio of total travelled distance and total time taken by the particle is known as average speed.

Vavg. = ∆X / ∆T
