Question

WHAT IS SI UNIT OF VELOCITY?EXPLAIN VELOCITY​

Answer 1

Answer:

Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s) or as the SI base unit of (m⋅s−1).

✒ 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.

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

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.
