JEE Mains · Physics · STD 11 - 2. motion in straight line
A particle starts from origin \(O\) from rest and moves with a uniform acceleration along the positive \(x -\) axis. Identify all figures that correctly represent the motion qualitatively. (\(a =\) acceleration, \(v =\) velocity, \(x =\) displacement, \(t =\) time)
- A \(a, b, c\)
- B \(a\)
- C \(b, c\)
- D \(a, b, d\)
Answer & Solution
Correct Answer
(D) \(a, b, d\)
Step-by-step Solution
Detailed explanation
\begin{array}{l} Give\,initial\,velocity\,u = 0\,and\,acceleration\\ is\,{\rm{constant}}\\ At\,time\,t\\ v = 0 + \,at\\ \Rightarrow \,v = \,at\\ Also\,X = 0\left( t \right) + \frac{1}{2}a{t^2}\\ \Rightarrow \,\,X = \frac{1}{2}a{t^2}\\ Graph\,\left( a \right),\,\left( b…
