Question

what is speed and velocity ??
plzz answer fast
I will mark as brainiest answer the first one​

Answer 1

Answer:

speed is the rate of change of distance with the time.......

velocity is the rate of change of displacement with time......

acceleration is the rate of change of velocity with time......

# hope it will help you I am also giving the definition of acceleration too......

Answer 2

$\blue{\bigstar}\:\:{\underline{\boxed{\bf\red{Speed}}}}$

⤇ Speed of a body is defined as the distance covered by per unit time.

• Speed = Distance/Time.
• SI unit of speed is m/s.
• CGS unit of speed is cm/s.
• Speed is a scaler quantity.
• It is always positive (+ve).
• Speed tells us how fast a body is moving.

$\green{\bigstar}\:\:{\underline{\boxed{\bf\pink{Velocity}}}}$

⤇ Velocity of body is is defined as the displacement covered by it's per unit time.

• Velocity = Displacement/Time.
• It is a vector quantity.
• SI unit of velocity is m/s.
• CGS unit of velocity is cm/s.

[Note:- Speed and velocity describe motion]
