2.Motion in Straight Line
medium
Velocity of a particle is in negative direction with constant acceleration in positive direction. Then, match the following columns.
| Colum $I$ | Colum $II$ |
| $(A)$ Velocity-time graph | $(p)$ Slope $\rightarrow$ negative |
| $(B)$ Acceleration-time graph | $(q)$ Slope $\rightarrow$ positive |
| $(C)$ Displacement-time graph | $(r)$ Slope $\rightarrow$ zero |
| $(s)$ $\mid$ Slope $\mid \rightarrow$ increasing | |
| $(t)$ $\mid$ Slope $\mid$ $\rightarrow$ decreasing | |
| $(u)$ |Slope| $\rightarrow$ constant |
A
$( A ) \rightarrow Q , T _{;}( B ) \rightarrow Q , S ;( C ) \rightarrow P , T$
B
$( A ) \rightarrow Q , U ;( B ) \rightarrow R , U ;( C ) \rightarrow P , T$
C
(A) $\rightarrow P , T ;( B ) \rightarrow R , U ;( C ) \rightarrow Q , S$
D
$( A ) \rightarrow P , T ;( B ) \rightarrow Q , U ;( C ) \rightarrow Q , T$
