explain types of velocity.​

Answer 1

$\huge \mathfrak \pink{Answer}$

$\Large\boxed{Types\:of\:Velocity}$

• Constant Velocity

An object with a constant velocity does not change in speed or direction. The only objects that qualify as moving at a constant velocity are those that move in a straight line at a steady speed. An object outside a solar system, in interstellar space, that is not under the influence of outside forces might be described as an object that moves with a constant velocity.

• Changing Velocity

Objects with changing velocity exhibit a change in speed or direction over a period of time. Changes in the velocity of objects are measured as acceleration. Objects with a constant speed and a changing direction are also accelerating. Comets and asteroids within the solar system are examples of objects with changing velocity since their speed or direction is influenced by gravity.

• Instant Velocity

Instant velocity is a method for determining how quickly an object is changing its speed or direction at a given point in time. Instant velocity is determined by reducing the period of time used to measure acceleration to such a small quantity that the object does not accelerate during the given period of time. This method of measuring velocity is useful for producing graphs measuring a series of changes in velocity.

• Terminal Velocity

Terminal velocity is a term used to describe the movement of an object falling freely through the atmosphere. Objects falling to the ground in a vacuum will constantly accelerate until they reach the ground. An object falling through the atmosphere, however, will eventually stop accelerating due to increasing amounts of air resistance. The point at which air resistance equals the acceleration caused by gravity -- or whatever force is acting on the object -- is known as terminal velocity.

Answer 2

$\sf\bold\green{{QUESTION:-}}$

✓✓explain types of velocity.

$\sf\bold\purple{{ANSWER:-}}$

$\sf\bold\orange{{(i)Uniform\: velocity:-}}$

★The displacement covered by the body in the equal interval of time.

$\sf\bold\red{{(ii)Non\:uniform\: velocity:-}}$

★A body cover un-equal Displacement in equal interval of time.

$\sf\bold\blue{{(iii)Average\: velocity:-}}$

★Average velocity is defined as the ratio of total displacement to the total time taken.

• $\sf\dfrac{Total\: displacement}{Total\:time\: taken}$

$\sf\bold\pink{{(iv)Intantaneous\: velocity:-}}$

★Velocity of a body at a particular time.
