प्रश्न
Define motion. What do you understand by the terms uniform motion and non-uniform motion ? Explain with examples.
उत्तर
A body is said to be in motion when its position changes continuously with respect to a stationary point taken as the reference point.
Uniform motion: A body is said to be in uniform motion if it travels equal distances in equal intervals of time in a particular direction, no matter how small these time intervals are.
For example, a car running at a constant speed of 10 m/s towards east will cover the equal distance of 10 m every second towards east, so its motion will be uniform.
Non-uniform motion: A body is said to be in non-uniform motion if it travels unequal distances in equal intervals of time.
For example, motion of a freely falling ball from the roof of a tall building.
