The average velocity of a particles is equal to its displacement-time graph ?

When is the average velocity of a particle equal to its instantaneous velocity?

The velocity of particle (whose displacement time graph is shown) at t=3 .

The velocity of particle (whose displacement time graph is shown) at t=3 .

Assertion: In successive time intervals if the average velocities of a particle are equal then the particle must be moving with constant velocity. Reason: When a particle moves with uniform velocity, its displacement always increases with time.

Show that the average velocity of a particle in uniform motion is equal to the slope of the corresponding time - displacement curve .

Assertion: Average speed of a particle in a given time interval is never less than the magnitude of the average velocity. Reason: The magnitude of the velocity (instantaneous velocity) of a particle is equal to its speed.
