Define three dimensional motion.

Which of the following is not true about the voids formed in three dimensional hexagonal close packed structure?

Figure 3.24 gives the x-t plot of a particle in one-dimensional motion. Three different equal intervals of time are shown. In which interval is the average speed greatest, and in which is it the least ? Give the sign of average velocity for each interval.

What do you mean by one dimensional motion?

The correct statement cubic close packed in three dimensional structure?

Look at the graphs (Fig. 3.20) carefully and state, with reasons, which of these cannot possibly represent one-dimensional motion of a particle.

A body is initially at rest .It undergoes one-dimensional motion with constant acceleration. The power delivered to it at time t is proportional to t

The velocity-time graph of a particle in one-dimensional motion is shown in Fig. 3.29 :- Which of the following formulae are correct for describing the motion of the particle over the time-interval:- v(t_2)=v(t_1) + a (t_2 - t_1)
