Question

List 1 gives a list of possible set of parameters measured in some experiments. The variations of the parameters in the form of graphs are shown in List 2. Match the set of parameters given in List 1 with the graph given in List 2. Indicate your answer by darkening the appropriate bubbles of the $4\times 4$ matrix given in the ORS.

Answer 1

A) take $x$ as displacement. $h$ as change in height.

$h=l(1-cos\theta )=l\times 2si{n}^2\theta /2$

$sin\theta /2=x/2l$

$U=mgh=mg{x}^2/2l$ quadratic

B) When at const. velocity: $s=vt$, when accelerating. $s=0.5a{t}^2$

linear or quadratic

C)$R=v^{2}sin2\theta /g=K{v}^2$ quadratic

D)$T=2\pi \sqrt{l/g}$

$T^2=kl$ linear
