Give one similarity and one dissimilarity between the two graphs
Similarity : Both graphs are velocity$-$time graph.
Dissimilarity : In first graph, a body starts its journey from rest with uniform rate while in second graph, a body starts journey with a specific velocity that increases at nonuniform rate.
The distance$-$time graph of a body is parallel to time axis. The body is
Four cars $A$, $B$, $C$ and $D$ are moving on a levelled road. Their distance versus time graphs are shown in Fig. Choose the correct statement
A cyclist driving at $36\, km h^{-1}$ stops his cycle in $2\, s$ by the application of brakes. Calculate $(i)$ retardation $(ii)$ distance covered during the application of brakes.
The speed-time graphs of two cars are represented by $P$ and $Q$ as shown below
$(a)$ Find the difference in the distance travelled by the two cars (in $m$ ) after $4\, s$.
$(b)$ Do they ever move with the same speed ? If so when ?
$(c)$ What type of motion car $P$ and $Q$ are undergoing ?
State the meaning of uniform circular motion.
