what is meant by uniform motion and non uniform motion ? give one example of uniform motion and one if non uniform motion
Answers
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.
More examples of non-uniform motion are: Oscillation of pendulum, the motion of a train, a person jogging in the park etc.
Answer:
Uniform motion :
If the body covers equal distance at fixed interval of time is called uniform motion.
Example of Uniform motion :
vibrating spring in a sewing machine.
A ship steaming on a straight course at steady speed.
A train going along the tracks at steady speed.
Nonuniform motion :
If the body covers do not equal distance at fixed interval of time is called uniform motion.
Example of Nonuniform motion :
Oscillation of pendulum.
The motion of a train.
A person jogging in the park
