A Physics teacher is explaining the difference between average speed and average velocity to her students. Where average velocity = ("displacement")/("time taken") , "average speed" = ("actual distance travelled")/("time taken") She emphasises that average speed is more relevant than average velocity, because displacement from one place to other is only theoretical, being the shortest distance between two places. Average speed is the real entity that matters, taking into account the actual time taken to travel the actual distance between the two stations. Read the above passage and answer the following question : (i) Do you agree with the statement of Physics teacher ? (ii) The shortest distance between Ambala to Delhi is 200 km . A train takes 4 hrs and covers a distance of 210 km in going from Ambala to Delhi via Karnal. Another train takes 5 hrs and covers 250 km distance in going from Ambala to Delhi via Saharanpur. What is the average speed of these two trains? What would be the average velocity of a train that takes 2.5 hrs to cover 200 km distance ? (iii) What values do you learn from this discussion ?

STATEMENT-1: The avergae speed the average velocity of the aprticles are different physical quantities. STATEMENT-2: The avergae speed and average velocity have same dimensions.

Statement-2: It is possible when the direction of motion keeps changing. Statement-1: Magnitude of average velocity is equal to average speed, if velocity is constant.

STATEMENT - 1 : A particle is projected vertically upwards with speed v. Starting from initial point, its average velocity is less than average speed than average speed when particle is returning back to ground. and STATEMENT - 2 : When particle turns back, its displacement is less than distance covered.

A particle starts moving from rest at t=0 with a tangential acceleration of constant magnitude of pi m//s^(2) along a circle of radius 6 m. The value of average acceleration, average velocity and average speed during the first 2 sqrt(3) s of motion, are respectively :
