Question

Q 2) Define speed and velocity of a body​

Answer 1

$\huge\mathfrak\red {Speed}$

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction. On the other hand, velocity is a vector quantity; it is direction-aware. Velocity is the rate at which the position changes.

Answer 2

Explanation:

Speed:

• Speed =distance travelled by object/time taken.
• Speed is a scalar quantity and it will be always positive.
• SI unit of speed is m/s.

Velocity:

• Velocity is the rate of change of displacement.
• Velocity is a vector quantity and can be negative, positive or zero.
• Its SI uint is m/s.
