Which of the following is an example of uniform motion?
A train moving at a constant speed on a straight track
In physics, uniform motion refers to the motion of an object moving at a constant speed in a straight line. This means that both the speed and direction of the object remain unchanged over time.
Let's evaluate the given options to determine which one represents uniform motion:
A ball rolling down a slope: The ball's speed changes due to acceleration from gravity, so this is not uniform motion.
A train moving at a constant speed on a straight track: The train maintains a constant speed and travels in a straight line, making this an example of uniform motion.
A sprinter running a 100-metre race with varying speed: The sprinter's speed changes during the race, so this is not uniform motion.
A vehicle moving through a crowded area: The vehicle's speed and direction likely change to navigate through traffic, meaning this is not uniform motion.
The correct example of uniform motion is therefore:
A train moving at a constant speed on a straight track
