A uniform motion is a type of motion during which an object covers an equal distance in an equal interval of time. In other words, when the speed of an object is constant throughout its motion, an object is said to be in uniform motion.
The opposite of uniform motion is non-uniform motion. A non-uniform motion is a type of motion during which an object covers an unequal distance in an equal interval of time. In other words, when the speed of an object is variable throughout its motion, an object is said to be in non-uniform motion.
Uniform Motion Examples in Daily Life (All New)
- A car on a long drive
- Motion of earth around the sun
- An airplane in the sky
- Motion of moon around the earth
- A high-speed train on a track
- An artificial satellite in its orbit
A car on a long drive
When you start a car, at first, the motion of a car is perfectly a non-uniform one. I mean, you start it from zero, then move ahead to speed it up. But, after some time, when you have achieved your desired speed, what you wanna do is go smoothly. And, when you do that your car is in a perfectly uniform motion.
Meaning, you are not speeding up, velocity becomes constant, and you are just going with the flow. However, you can’t go on forever like this. I mean there will come a time when you have to increase or decrease your speed. And, when you do that, you are back into the non-uniform motion.
Motion of Earth Around the Sun
You already know that our planet earth completes one revolution around the sun in approximately 365 days 5 hours 59 minutes and 16 seconds. A time period in our normal day-to-day life is known as a calendar year that never changes. Ever wondered why???
Because the earth is revolving around the sun in a uniform circular motion. Obviously, you would be thinking if the earth is revolving around the sun in a uniform motion then why do some years have 365 days and some have 366 days?
Well, this happens because we adjust the extra 5 hours and 59 minutes, and 16 seconds after every four years. And, this is how we get a leap year (366 days) after every four years. Just to let you know that all the planets in our solar system revolve around the sun in a uniform circular motion.

An airplane in the sky
Just like a car on a long drive, an airplane in the sky can easily travel at a uniform speed. When a plane takes off, it starts from zero. But when it is flying in the sky at the desired altitude and speed, this is the time when it can fly at a steady-state uniform motion.
Not to mention, while landing, it will again go back to its non-uniform speed. A sailing ship is also an example of uniform motion. The formula is the same. At the start, it will execute a non-uniform motion. After achieving the desired speed, a sailing ship will execute uniform motion by maintaining its steady speed.

Motion of Moon around the Earth
In order to complete a revolution around the earth, our natural satellite takes exactly 27 days. Yup, your guess is right. It simply happens because the moon revolves around the earth in a uniform circular motion. However, just to let you know, in reality, the moon does not revolve around the earth in a uniform circular motion.
Our esteemed scientists and astronomers have calculated that the moon is moving away from earth at the rate of 4 cm per year. Therefore, as a result, one can say that the motion of the moon is not a perfect uniform circular motion.
However, the speed at which the moon is spinning away from the earth is the same speed at which our fingernails grow. Therefore, it can be easily neglected. I mean, in other words, it would take billions of years for the moon to completely move away from the earth.
A high-speed train on a track
Just like cars and airplanes, there comes a time when a high-speed train running on a track can achieve a steady-state uniform motion. Well, as you would already have guessed the formula will remain the same.
At first, it will start from zero, then after achieving the desired stable speed, a train will maintain it for some time before stopping at some junction.

An artificial satellite in its orbit
We all know the importance of satellites in today’s world. I mean without satellites revolving in their orbit, half of the world will go blind. Just to let you know that nowadays our very internet is working because of the use of satellites.
Well, not only the internet, our GPS, Weather forecasting system and so many other devices work because of the satellites that revolve around the earth in a uniform circular motion.
When we launch a satellite, its motion is totally a non-uniform one. However, after reaching the Lagrange point of its orbit around the earth, it continues to rotate in a uniform steady-state circular motion. It will continue to maintain its uniform motion until it will run out of its fuel.
