2.Motion in Straight Line
easy
Match the following columns.
| Colum $I$ | Colum $II$ |
| $(A)$ $\frac{dv}{dt}$ | $(p)$ Acceleration |
| $(B)$ $\frac{d|v|}{dt}$ | $(q)$ Magnitude of acceleration |
| $(C)$ $\frac{dr}{dt}$ | $(r)$ Velocity |
| $(D)$ $\left|\frac{d r }{d t}\right|$ | $(s)$ Magnitude of velocity |
A$( A \rightarrow p , B \rightarrow q , C \rightarrow r , D \rightarrow s )$
B$( A \rightarrow q , B \rightarrow p , C \rightarrow r , D \rightarrow s )$
C$( A \rightarrow r , B \rightarrow q , C \rightarrow p , D \rightarrow s )$
D$( A \rightarrow s , B \rightarrow q , C \rightarrow r , D \rightarrow p )$
Solution
(a)
$\frac{d| v |}{d t}$ is rate of change of speed of the particle.
$\frac{d| r |}{d t}$ is the rate by which distance of particle from the origin is changing.
$\frac{d| v |}{d t}$ is rate of change of speed of the particle.
$\frac{d| r |}{d t}$ is the rate by which distance of particle from the origin is changing.
