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

Under what condition will the distance and displacement of a moving object have the same magnitude?

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?

Write the difference between speed and velocity.

State the condition resulting in reverse osmosis.

Distinguish between speed and velocity.

State one condition for sustained interference pattern.

An object of mass 100 kg is accelerated uniformly from a velocity of 5 m s^-1 to 8m s^-1 in 6 s. Calculate the initial and final momentum of the object. Also, find the magnitude of the force exerted on the object.

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