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 metres distance with in time t (8 seconds). Here, the car starts from O and after 2 seconds it reaches position A covering a distance of 4 meters from the origin as shown. In next 2 seconds it reaches position B covering a distance of 8 meters from origin and in next 2 seconds it reaches C covering a distance of 12 meters from origin and in next 2 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 8 second interval. It means that the distance covered by the car is directly proportional to the time. From this illustration we can conclude that, the car was travels equal distances in equal intervals of time. We can say that the motion is called uniform motion.
Another example: Consider, a car moves from one position to another position about 30 metres distance with in time t (10 seconds). Here, the car starts from O and after 2 seconds it reaches position A covering a distance of 2 meters from the origin as shown. In next 2 seconds it reaches position B covering a distance of 8 meters from origin and in next 2 seconds it reaches C covering a distance of 10 meters from origin and in next 2 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 2 second interval. From this illustration we can conclude that, the car was travels unequal distances in equal intervals of time. We can say that the motion is called Non-uniform motion.
