Most Understandable Guide on Uniform Motion and Non-Uniform Motion With Definition and Examples

The human body’s movement is motion. The most common feature of a moving body is that it changes its position in time. This article focuses on motion, and the types of motion, such as uniform and non-uniform motion, with examples for clear understanding.

In our daily lives, we see various motions of non-living and living objects like cars, fishes, birds, trains, and so on. There are millions of objects around us. Some are in a state of rest, while others exhibit motion. A body is considered in motion if its position is constantly changing in relation to a stationary object used as an example of a reference point. 

We are all aware that the most common feature of all moving bodies is that they alter their positions with the passage of time. For instance, if the car’s location is constantly changing in relation to stationary objects such as schools or houses, and so on. Then a car is moving or is in motion. 

The motion could be of two kinds, i.e. uniform motion and non-uniform movement. This article will teach about motion and its forms and types, with a few examples.

Uniform Motion

Let’s begin with the simplest question, what is uniform motion and non uniform motion? A body is said to move in a uniform manner when it travels at the same distances over equal time intervals regardless of how small the time intervals might be.

If we draw distance-time graphs for uniform motion, then it will be a straight line. To understand it better, let’s take a car as an example. A car running at a constant speed, say 20 meters per second. It will cover the same distances of 20 meters every second, and the car’s motion will be uniform.

Examples of Uniform Motions:

  • The hour hand on our clocks is moved with a uniform speed, concluding the movement of a certain distance within an hour
  • A vessel cruising along with straight courses at a steady speed
  • A car driving on a straight, level road at a steady pace
  • An aircraft that is flying at a constant height, and a constant speed
  • A cooling fan operating at a set speed
  • The Sun’s movement around the Earth is a uniform motion.
  • A train is moving through the tracks at a constant speed.
  • Movement of fan
  • A vibrating spring inside the sewing machine
  • A pendulum that has equal magnitudes on both sides

Let’s go over a few of them-

A cruising plane at a steady pace and an aircraft operating at a steady speed is travelling at a consistent speed, which means they travel the same distances at regular intervals. Certain elements like turbulence, turning, landing, etc., could cause a deviation in speed that’s not uniform. In constant speed conditions, while cruising, we could consider it as an example of uniform motion.

Another example is the blades on a propeller or fan. If you’ve observed the blades of a fan, they are rotating at the same speed. They do not alter their speed unless a regulator changes them. So, the blades move equally in fixed intervals, which is also an example of uniform motion.

The rotation that revolves around the Earth in relation to the Sun is rotated around the Sun each day for 365 days, 5 hours, 59 minutes, plus 16 seconds. So, Earth travels at the same distance at fixed intervals. It’s not the norm that the Earth revolves within 200 days, and the next time it is 365 days.

Examples of Non-Uniform Motions:

  • A horse participating in an event
  • A bus travelling through the market
  • A ball that bounces
  • The movement of an asteroid
  • Aircraft moving through clouds before landing
  • A box is being dragged off an area
  • A man is running 100 meters
  • A car slowing to a stop
  • Trains coming to their end-of-the-line sop
  • The collision of a car with another
  • In the above examples, it is the speed that varies

Non-Uniform Motion

A body is considered moving in a non-uniform movement if it covers uneven distances over equally long intervals. For instance, if we throw a ball off the roof of a high building, we’ll see that it travels over different distances over equally long intervals. As an example, 5 metres in the first second and 15 metres in the second and so on. 

Therefore, a falling ball will cover smaller distances within the first “1-second’ interval and greater distances during the subsequent 1-second intervals. So, it is possible to say that the movement of a moving body can be described as an example of a non-uniform movement. The graph of the distance-time of the non-uniform motion is a curving line.

Let’s look at a few examples.

  • A plane taking off and landing

A plane that is taking off and landing is another illustration of a non-uniform movement. There is no surprise that there will come times when an aircraft exhibits a uniform motion. This only occurs when it is flying through the sky at the appropriate speed. This means the plane can fly at a steady-state uniform speed.

However, before reaching the desired altitude, the aircraft must accelerate from a halt. In addition, when it lands, the aircraft will need to reduce its speed. As a result, it will display the motion as a non-uniform one.

  • Batsmen hitting balls

Moving forward as a batsman hits the ball, initially, the ball is moving at high speed. But once the ball begins to move toward the boundary line, the speed decreases as time passes.

Summarised Notes for Uniform and Non-Uniform Motion

  1. Motion can be classified into non-uniform and uniform motion.
  2. There is zero acceleration in a uniform motion.
  3. A body moving in a uniform manner covers equal distances over equally long intervals of time.
  4. The acceleration is not zero in non-uniform motion.
  5. A body that is not uniform in motion covers uniform distances at different periods.


Everyone knows that motion in our lives plays a crucial role. It is dependent on the object and how long it will require to complete the distance. Fast objects will cover the distance faster, whereas slow objects take a longer time to cover it. You learned in this article that uniform or non-uniform motion is dependent on the speed of the body moving, regardless of whether it is moving or not.
