Question

From the following, find the pair of physical quantities which are analogous to one another in translatory motion and rotatory motion:

• A. Mass, Moment of inertia
• B. Force, Torque
• C. Linear momentum, Angular momentum
• D. All of these

Answer 1

Answer: (D)

All of these

$F=ma$
$T=I\alpha$
$F\to T$
$m\to I$
$a\to \alpha$
$P\to L$
$R\Rightarrow$ Force, $T=$Torque, $m=$Mass,
$T\Rightarrow$ moment of Inertia, $a=$acceleration,
$\alpha \Rightarrow$ angular acceleration $P=$momentum
$L\to$ Angular momentum.
