Question

what is uniform and nonuniform motion​

Answer 1

Answer:

Uniform and Non-Uniform Motion

Explanation:

In our day to day life we observe several motions of living and non-living objects, whether birds, fishes, cars, trains, etc. Millions of objects are surrounding us, some stays at rest while some shows motion. A body is said to be in motion when its position changes continuously with respect to a stationary object taken as a reference point. We all know that the common characteristic of all the moving bodies is that they change their position with time. For example, when the position of car changes continuously with respect to some stationary objects like houses or schools etc. we say that a car is moving or car is in motion. Motion can be of two types i.e. uniform motion and non-uniform motion. Through this article we will learn about motion, its types with some examples.

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. If we draw distance time graph for uniform motion then it will be straight line. For better understanding we can take an example, 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.More examples of Uniform motion are: Movement of hands of a watch, Rotation and revolution of the earth, Movement of the blades of a ceiling fan etc.

Non-Uniform Motion

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 2

Answer:

Uniform motion- The motion in which the object travels the same distance in the same interval of time.

Non-uniform motion - The motion in which the object travels same distance in different intervals of time.
