What can you conclude about the motion of a body depicted by the velocity$-$time graphs $(i),(i i)$ and $(i i i)$ given below

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 ?

$(a)$ Which type of motion is represented by the velocity$-$time graph shown below ?

$(b)$ Name the physical quantity which can be calculated by the area of rectangle $OABC$.

$(c)$ What does the straight line $AB$ represents ?

Give examples to distinguish

$(i)$ Distance and displacement.

$(ii)$ Speed and velocity.

$(iii)$ Acceleration and retardation.

What is meant by uniform motion ? Can you think of an example of a body in uniforim motion ?
