Answer:
Motion and Time begins by introducing different types of motion by citing a few examples. In the first section of the chapter, Motion and Time, the concept of speed is explained in detail. Here, the formula for calculating the speed of an object along with a difference between uniform motion and non-uniform motion is provided. In the next section, the concept of measurement of time is taken into consideration. Moreover, the term periodic motion is explained with the help of simple pendulum. Apart from this, the oscillatory motion of the pendulum and time period is also defined. An activity illustrating the method to calculate the time period of a simple pendulum is also included here. The third section of the chapter, Motion and Time talks about units of time and speed. The fourth section discusses the method to measure the speed of the object with a mention of a speedometer. A short note on some ancient time measuring devices is provided. In the last section of the chapter, Motion and Time, the distance-time graph is explained extensively.
