Question

Figures show the displacement-time graphs of two particles moving along the x-axis. We can say that (A) Both the particles are having a uniformly retarded motion (B) Both the particles are having a uniformly accelerated motion (C) Particle (i) is having a uniformly accelerated motion while particle (ii) is having a uniformly retarded motion (D) Particle (i) is having a uniformly retarded motion while particle (ii) is having a uniformly accelerated motion

It means velocity goes on increasing. So this depicts uniform acceleration. In Fig. (ii) the slopes at 4, 5, 6 go on decreasing. It means velocity goes on decreasing. So this depicts uniform retardation.

Q. Figures show the displacement-time graphs of two particles moving along the x-axis. We can say that

Both the particles are having a uniformly retarded motion

Both the particles are having a uniformly accelerated motion

Particle (i) is having a uniformly accelerated motion while particle (ii) is having a uniformly retarded motion

Particle (i) is having a uniformly retarded motion while particle (ii) is having a uniformly accelerated motion

In Fig. (i) the slopes at 1, 2, 3 go on increasing. It means velocity goes on increasing. So this depicts uniform acceleration. In Fig. (ii) the slopes at 4, 5, 6 go on decreasing. It means velocity goes on decreasing. So this depicts uniform retardation.
