For the motion on a straight line path with constant acceleration the ratio of the maqnitude of the displacement to the distance covered is
$\geq 1$
$\leq 1$
$<1$
$=1$
A person travelling in a bus noted the timings and the corresponding distances as indicated on the km stones. (a) Name this type of table $(b)$ What conclusion do you draw from this data ?
Time | Distance |
$8.00\, am$ | $10\, km$ |
$8.15 \,am$ | $20 \,km$ |
$8.30\, am$ | $30\, km$ |
$8.45\, am$ | $40\, km$ |
$9.00\, am$ | $50\, km$ |
By giving an example, prove that rest and motion are relative terms.
Why does (second)$^{2}$ occur in the unit of acceleration ?
Write true or false for the following statements
A quantitv which can be represented completely by magnitude alone is called a vector quantity.
A car travels $100\, km$ east and then $100 \,km$ south. Finally, it comes back to the starting point by the south-east route. Throughout the journey the speed is constant at $60\, km h ^{-1}$. The average velocity for the whole journey if time taken is $3.3$ hours is
