Measurement of Speed

Discuss in which direction will the smoke from the engine of an electric train escape, if the train is going from north to south.

For a body in uniform motion, the distance-time graph is a _____.

Define uniform and non-uniform motion.

The standard unit of speed is

A car is moving at a speed of $30 \mathrm{k}\mathrm{m}/\mathrm{h}$ and a truck is moving at a speed of $40 \mathrm{k}\mathrm{m}/\mathrm{h}$. The distance-time graph will show

Speed is calculated as

The figure given alongside represents the distance-time graph for the motion of three moving bodies $\mathrm{A}$, $\mathrm{B}$ and $\mathrm{C}$. Which of them is the fastest moving body and which one is the slowest moving body? 

A bus takes $2 \mathrm{h}\mathrm{r}$ to cover a distance of $80 \mathrm{k}\mathrm{m}$. Calculate its speed in $\mathrm{k}\mathrm{m}/\mathrm{h}$ and $\mathrm{m}/\mathrm{s}$.

What is meant by slow and fast motion?

The distance covered by a cyclist is given in the following table. Represent it in the form of a line graph and calculate his speed.

The speed of a train is faster than a car. How will you prove this statement? What physical quantities do you require to answer this question?
