Question

define speed and type of speed ?​

Answer 1

$\small{\underline{\underline{\mathbf{SPEED-}}}}$

✒ 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

✡ $\bold{it\: is\: scalar\: quantity}$

✡ $\bold{it\: never\: be\: negative}$

✡ $\bold{it\: may\: increase,\: decrease\: or\: remains\: constant\: with\: respect\: to\: time. }$

$\small{\underline{\underline{\mathbf{TYPES\:OF\:SPEED-}}}}$

1.$\small\bf{\underline{Uniform\: speed-}}$

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

2.$\small\bf{\underline{Non-\:Uniform\: speed-}}$

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

3.$\small\bf{\underline{Average\: speed-}}$

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

Vavg. = ∆X / ∆T

Answer 2

Answer:Speed is the distance covered per unit time

Explanation:Speed=distance

-------------

Time

Different types of speed = Average speed

=Total distance

--------------------

Time taken

Average speed is the total distance covered by per unit time. PLEASE MARK IT AS BRAINLEST.
