C It’s the shortest distance between initial & final position 

D It is a vector quantity

Statement A: When a body moves with uniform speed, then the average speed is same as instantaneous speed. 

Statement B: Average speed is less than average velocity. 

Which of the above statement is true

A car is moving with uniform speed and covers 100m in 50 second find the speed.

Instantaneous speed of a vehicle is measured by

A particle covers equal distance in equal interval of time. It is said to be

Statement A: A curved line in a speed – time graph means non-uniform motion. 

Statement B : A curved line in a velocity – time graph means uniform acceleration

A train 120m long moving on a straight and level track with uniform speed passes a pole in 6 seconds. Find the time it will take to cross a 50m long bridge.

(1) Speed 

(2) Velocity 

(3) Acceleration 

(4) Average speed 

(A) Displacement / Time taken 

(B) Total distance covered / Total time taken 

(C) Change in velocity / Time taken 

(D) Distance covered / Time taken
