Distance$-$time graph below represents the motion of two buses $A$ and $B$
$(i)$ What is the distance by which bus $B$ was ahead of bus $A$ initially ?
$(ii)$ Do they ever meet each other ? If so, when ?
$(iii)$ What is the distance travelled by bus $A$ when it overtakes bus $B$ ?
$(iv)$ Find out the distance by which bus $A$ was ahead of bus $B$ at $y=12 h$
$(v)$ Which one of them is moving faster ? Give reason.
$(i)$ $20 km$
$(ii)$ Yes, they meet after $9$ hour.
$(iii)$ $60 km$.
$(iv)$ $80-70=10 km$
$(v)$ $A$ moves faster as its slope is higher than $B$.
$(a)$ Differentiate between uniform linear and uniform circular motion.
$(b)$ Write any four examples of uniform circular motion.
$(c)$ Is uniform circular motion is accelerated motion ?
For the motion on a straight line path with constant acceleration the ratio of the maqnitude of the displacement to the distance covered is
Name a physical quantity that essentially changes as a body moves.
If the displacement$-$time graph for a particle is parallel to time axis, what is the velocity of the particle ?
An object is moving with uniform speed in a circle of radius $7\, m .$ Calculate the distance and displacement when it completes half the circle. What type does the object possess ?
