How can you find the distance travelled by body in uniform motion from the velocity$-$time graph ?
Differentiate between distance and displacement.
The following table show os the positon of three persons between $8.00\, am$ to $8.20\, am$.
Time | Position (in $km$) | ||
Person $A$ | Person $B$ | Person $C$ | |
$8.00 \,am$ | $0$ | $0$ | $0$ |
$8.05 \,am$ | $4$ | $5$ | $10$ |
$8.10\, am$ | $13$ | $10$ | $19$ |
$8.15 \,am$ | $20$ | $15$ | $24$ |
$8.20\, am$ | $25$ | $20$ | $27$ |
$(i)$ Who is moving with constant speed ?
$(ii)$ Who has travelled maximum distance between $8.00\, am$ to $8.05\, am$ ?
$(iii)$ Calculate the average speed of person $'A^{\prime}$ in $k m h^{-1}$
In your everyday life, you come across a range of motions in which
$(a)$ acceleration is in the direction of motion.
$(b)$ acceleration is against the direction of motion.
$(c)$ acceleration is uniform.
$(d)$ acceleration is non$-$uniform.
Can you identify one example each of the above type of motion ?
A cyclist goes once around a circular track of diameter $105$ metre in $5$ minutes. Calculate his speed.
