We have carefully distinguished between average speed and magnitude of average velocity. No such distinction is necessary when we consider instantaneous speed and magnitude of velocity The instantaneous speed is always equal to the magnitude of instantaneous velocity. Why?

For a particle in one dimensional motion, the instantaneous speed is always equal to the magnitude of instantaneous velocity. Why?

Distinguish between speed and velocity.

Distinguish between average velocity and instantaneous velocity.

When is the average speed of an object equal to the magnitude of its average velocity?

State the condition when the magnitude of velocity and speed of an object are equal.

Under what conditions is the average velocity equal to instantaneous velocity.

Distinguish between average velocity and average speed. Is it possible that the average velocity of a body is zero, but its average speed is non-zero?

For a body moving along a straight line, the average velocity is equal to its instantaneous velocity. The motion of the body is

A passenger arriving in a new town wishes to go from the station to a hotel located 10 km away on a straight road from the station. * A dishonest cabman takes him along a circuitous path 23 km long and reaches the hotel in 28 min. What is (a) the average speed of the taxi, (b) the magnitude of average velocity? Are the two equal?

A man walks on a straight road from his home to a market 2.5 km away with a speed of 5 km h ^-1 . Finding the market closed, he instantly turns and walks back home with a speed of 7.5 km h^-1 . What is the magnitude of average velocity.
