Understanding Uniform Motion
Uniform motion refers to the motion of an object moving at a constant speed in a straight line. This means that the object covers equal distances in equal intervals of time, without any change in velocity.
Why Option D is Correct
- A bicycle moving at a constant speed on a straight road is the perfect example of uniform motion because:
- Constant Speed: The bicycle maintains the same speed throughout its journey.
- Straight Path: The movement occurs in a straight line, which is essential for uniform motion.
Analysis of Other Options
- A car accelerating from rest (Option A):
- Variable Speed: The car’s speed is changing as it accelerates, which means it does not maintain a constant speed.
- A roller coaster going up and down hills (Option B):
- Changing Speed and Direction: The speed and direction of the roller coaster change constantly due to the incline and decline of the tracks.
- A ball falling freely under gravity (Option C):
- Acceleration: The ball accelerates as it falls, meaning its speed increases over time, which disqualifies it from being uniform motion.
Conclusion
In summary, option D is the only scenario that meets the criteria for uniform motion, as it involves constant speed and straight-line movement. Understanding these distinctions is crucial for topics related to motion in physics and can aid in preparing for exams like the Delhi Police Constable category.
