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

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?

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

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

Distinguish between average velocity and instantaneous velocity.

Read each statement below carefully and state with reasons and examples, if it is true or false, particle in one-dimensional motion A./with zero speed at an instant may have non-zero acceleration at that instant

Define the terms instantaneous velocity and instantaneous acceleration.

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?

The displacement of a particle ( in meter ) moving along x axis is given by x = 18 + 5t^2 . Calculate the instantaneous velocity at t = 2S and instantaneous acceleration.

Can there be a two dimensional motion even though acceleration is present in only one direction?
