Explanation Given data: Refer to the FIGURE Q10.24 in the textbook for the potential-energy diagram of the particle. Explanation: In the given figure, the horizontal axis represents the particle’s position and the vertical axis represents the energy in terms of joules. The blue curve represents the particle’s potential energy with respect to the various positions. Consider the horizontal line (at the top of the co-ordinate axis) at which the potential energy is maximum value as energy line. At x = A : From the given Figure, the potential energy is maximum at x = A . The kinetic energy is the distance between the potential energy curve (blue curve) and the energy line (top horizontal line). The particle is rest at the starting point. Therefore, the kinetic energy is zero at x = A . From x = A to x = B : From the given figure, the potential energy line is decreasing and the distance between potential energy curve and energy line is increasing. Therefore, the potential energy decreases and kinetic energy increases from x = A to x = B . As the kinetic energy increases from x = A to x = B , the speed of the particle increases from the position A to B. From x = B to x = C : From the given figure, the potential energy line is still decreasing and the distance between potential energy curve and energy line is still increasing. Therefore, the potential energy decreases further and kinetic energy increases even more from x = B to x = C
