Question

Define speed and velocity. ​

Answer 1

Answer:

Speed

Distance per unit time is known as the speed of the body.

It is a scalar quantity.

It's SI unit metre/second.

Velocity

Displacement per unit time is known as the velocity of the body.

It is a vector quantity.

It's SI unit is metre/second.

Answer 2

$\huge\sf{Answer:-}$

SPEED

• If an object moves in relation to time relative to other objects, then this state of the object is called motion.

• The speed is also know was the action or motion.

VELOCITY

• Velocity means movement in a direction.

• This is a vector sign. The velocity of an object can vary in different directions.

• The rate of change of position of an object is called velocity.

• The speed, if written along the direction, is the same as the velocity, for example 60 km / h north.

• Velocity is an important part of dynamics, which is a branch of mechanics in which the motion of objects is studied.
