Physics - Kinematics Question with Solution | TestHub
Each entry of List-I shows a graph of a particle's one-dimensional motion. Match the entries of List-I with entries of List-II.
List-I | List-II |
|---|---|
| (1) Particle must change its direction during the subsequent motion |
| (2) Particle may return to its initial position during subsequent motion |
| (3) Acceleration vector of a particle must be constant throughout the motion |
| (4) Particle come to rest at least once during its motion |
- | (5) Initial velocity of particle is zero. |
Options:
Answer:
Solution:
(P) Position-time parabola: velocity changes sign (direction changes), particle returns to start, acceleration is constant and negative, and at the top - P.
(Q) Speed-time: initial speed non-zero, particle can return, speed becomes zero once - Q.
(R) Acceleration-time: area gives only, so return is possible; acceleration is not constant - R.
(S) Distance-time: distance has no direction, return is possible; slope = speed - S.
Hence option (D).
