Question

what is difference between speed and velocity?​

Answer 1

Answer:

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

${\green{\underline{Difference \:between\: speed\: and\: Velocity}}}$

$\huge{\pink{\underline{\underline{Speed}}}}$

➡️It is the distance covered by the body per unit time.

➡️Speed is scalar quantity.

➡️The average speed of a moving body can never be zero.

➡️Speed gives an idea about rapidity of motion of a body.

➡️Speed of a moving body can never be negative.

$\huge{\pink{\underline{\underline{Velocity}}}}$

➡️It is the displacement of the body per unit time.

➡️ Velocity is a vector quantity.

➡️The average velocity a moving body can be zero.

➡️ Velocity gives an idea about rapidity as well as position of body in motion.

➡️ Velocity of a moving body can be positive , negative or zero.

Additional information:

Speed: The distance an object is moving over a certain period of time.

• Speed tells you how fast or slow the object is moving.

$speed = \frac{distance \: travelled \: }{time \: taken}$

SI unit of speed = m/s

CGS unit of speed = km/h

Velocity: Velocity is a measure of speed and Direction of the motion if an object.

• As it is measuring both speed and direction it is a vector quantity.

• The velocity magnitude is given as displacement over time.

$velocity = \frac{displacement}{time}$

SI unit of velocity = m/s

CGS unit of velocity = cm/s
