Motion 2 - SS1 Physics Past Questions and Answers - page 3

One application of motion in a straight line in everyday life is the motion of vehicles on roads. When a car or any other vehicle moves along a straight road, it exhibits motion in a straight line. This application is significant as it allows for efficient transportation and connectivity between different locations. The motion of vehicles on roads is essential for commuting, transportation of goods, and various other activities. It enables people to travel from one place to another quickly and conveniently. The straight paths of roads allow vehicles to maintain a constant speed and direction, making the journey smoother and more predictable.

An example of an activity that involves motion in a straight line is running on a track. When a person runs on a straight track, they exhibit motion in a straight line. This activity can be used to illustrate concepts of speed and distance.

Speed is a measure of how quickly an object, in this case, the runner, covers a certain distance. In running, the speed can be determined by dividing the distance covered by the time taken. 

Distance, on the other hand, refers to the total length covered by the runner during the activity. In the context of running on a track, the distance can be measured by the length of the track itself.
