non uniform motion write an example for each question answer
Answers
Answer:
A body is said to be in a non-uniform motion if it travels unequal distances in equal intervals of time. For example, if we drop a ball from the roof of a tall building, we will notice that it will cover unequal distances in equal intervals of time. Like, 5 metres in the 1st second, 15 metres in the 2nd second and so on. Thus, a freely falling ball will covers smaller distances in the first ‘1 second’ and larger distances in the later ‘1 second’ intervals. Therefore, we can say that the motion of a freely falling body is an example of a non-uniform motion. The distance-time graph of the non-uniform motion is a curved line. Non-Uniform motion is also known as accelerated motion.
Answer:
An object moving along a straight line path is said to have non uniform motion if its speed keeps changing ( it does not remain constant ). An object having non uniform motion travels 'unequal distances' in 'equal intervals of time'.
For example :-
The motion of a train starting from a railway station is an example of non uniform motion. This is because when a stationary train starts from a railway station, its speed goes on increasing and it covers more and more distance in each '1 second' time interval.
