Question

3. Define uniform and non-uniform motion. Write one example for each​

Answer 1

Explanation:

uniform motion means when an object covers equal distance in equal interval of time for example the spinning of the giant wheel or fan and car moving at constant speed.........

non-uniform motion means when an object covers an equal distance and an equal distance of time for example a car moving at an unconstant speed

hope it helped .....pls mark me as brainliest..... pls follow me.....❤️❤️

Answer 2

Answer:

1. Uniform motion:- A body is said to be in uniform motion if it travels equal distances in equal intervals of time, no matter how small these time intervals may be.

e.g. a car is running at a constant speed say 20 metres per second, will cover equal distances of 20 metres, every second, so its motion will be uniform.

2. Non-uniform motion:- A body is said to be in a non-uniform motion if it travels unequal distances in equal intervals of time.

e.g. 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.
