Question

Explain the concept of velocity

ASAP......​

Answer 1

Answer:

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).

✒Velocity

• Velocity is defined as speed of an object in particular.
• SI unit of velocity is m/s.
• It is a vector quantity.
• Velocity = Displacement/time.

$\boxed{ \huge{{ = > v = \frac{s}{t} }}}$

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

✒ There are two types of velocity

1. Uniform Velocity

2. Non-uniform Velocity

Let understand the concept of velocity in detail.

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

✏ Uniform Velocity :-

When object cover equal distances in equal interval of time then uniform velocity take place.

✏ Non-uniform Velocity :-

When object cover an unequal distances in equal interval of time then non-uniform velocity take place.

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

-: Addition Information :-

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

✒Velocity of an object can be changed by :-

⭐ Changing the speed of object.

⭐ Changing direction of body.

⭐ Changing both time and direction of object. (Both)

✒ Average Velocity :-

• 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.

$\boxed{ \huge{Vav = \frac{u + v}{t} }}$

$\bold{\Huge{\boxed{{{Note}}}}}$

⭐ u = Initial Velocity

⭐ v = Final Velocity

⭐ t = time

⭐ s = Displacement (Use here)

⭐ Vav = Average Velocity
