UNIFORM MOTION & NON UNIFORM MOTION

Uniform motion and non uniform motion. A body is said to be in uniform motion if it travels equal distances in equal intervals of time. A body is said to have non uniform motion if it travels unequal distances in equal intervals of time. For example, consider a car moves from one position to another position about 16 meters distance within time T 8 seconds. Here, the car starts from O and after two seconds, it reaches position a covering a distance of four meters from the origin as shown. In next two seconds, it reaches position B covering a distance of 8 meters from origin and in next two seconds it reaches C covering a distance of 12 meters from origin and in next two seconds it reaches D covering a distance of 60 meters from origin. In this case, the car covers a total distance of 16 meters in 8 seconds with equal intervals of two seconds. It means that the distance covered by the car is directly proportional to the time. From this illustration, we can conclude that the car had traveled equal distances in equal intervals of time. So this type of motion is known as uniform motion. Another example, consider a car moves from one position to another position about 16 meters distance within time T 8 seconds. Here, the car starts from O and after two seconds, it reaches position a covering a distance of two meters from the origin as shown. It reaches position B covering a distance of 8 meters from origin and in the next two seconds, it reaches C covering a distance of ten meters from origin and in next two seconds, it reaches D covering a distance of 16 meters from origin. In this case, the car covers a distance of 16 meters in each two second interval. From this illustration we can conclude that the car had traveled unequal distances in equal intervals of time. So this type of motion is called as nonuniform motion.
