When you think of circular motion, the classic example of a uniform circular motion is an object traveling at a constant speed in a perfect circle.
However, this is not the only type of circular motion – there are also examples of non uniform circular motion. Non uniform circular motion is defined as motion in a circle at varying speeds, directions, or both.
This type of motion is incredibly common and can be seen in everyday life. This blog post will explore 9 real-life examples of non uniform circular motion in physics.
But before you read any further, it might be a good idea to briefly understand the concept of non uniform circular motion. It will help you to understand the examples better. If you are already familiar with the concept, you can skip it by clicking on the link below.
What is Non-uniform circular motion In Physics?
Definition
The non-uniform circular motion refers to the motion of an object moving in a circular path at varying speeds. In a uniform circular motion, an object travels along a circular path with a constant speed, but in a non uniform circular motion, the object’s speed changes at different points along the path. This means that the object’s velocity is not constant, as both the magnitude and direction of its velocity vector change.
An example of non-uniform circular motion is a car moving along a curved road at varying speeds. As the car turns, its speed may increase or decrease, and it experiences an acceleration directed towards the center of the circle, known as centripetal acceleration. This acceleration is responsible for keeping the car on its curved path.
Now let’s move on to explaining 9 non uniform circular motion examples in physics.

I am sure that the concept of uniform acceleration is clear to you now. If not, you can comment below. Let us now move on to 10 examples of uniform circular motion in physics & in real life.
Examples
- Ice skater performing a spin:
When an ice skater spins, their speed of spinning can change because they adjust their body position. This means they might spin faster or slower at different moments. This changing speed during the spin is an example of non-uniform circular motion. It’s like they’re not going at a constant speed in a circle; instead, their speed varies as they spin. - The spinning of Yo-Yo:
Had you ever played with a yo-yo as a kid? You would spin it over and over again, enjoying the motion without really knowing how it worked. Well, the yo-yo is actually a great example of something called non-uniform circular motion, which means it doesn’t spin at the same speed all the time. Sometimes it spins fast, other times it slows down.
When a yo-yo goes up and down, its motion is not consistent with speed in a perfect circle. Instead, the yo-yo’s speed changes at different points in its trajectory. As it moves downward, the yo-yo accelerates due to gravity, increasing its speed. When it reaches the bottom and starts moving back up, its speed decreases as gravity slows it down. This variation in speed during different phases of the yo-yo’s movement represents non-uniform circular motion. - A car traveling along a curved road: When a car travels along a curved road, it can experience non-uniform circular motion. This means that its speed may vary as it moves along the curve. As the car enters the curve, it may slow down, and as it exits the curve, it may accelerate. The changing speed during different sections of the curved road indicates non-uniform circular motion. It’s similar to how the car adjusts its pace to match the curvature of the road, resulting in variations in its speed while maintaining a circular path.
- A roller coaster loop: During a roller coaster loop, the motion showcases non-uniform circular motion. As the roller coaster approaches the loop, it gains speed, providing momentum for the climb. However, as it ascends, the speed gradually decreases due to the effects of gravity. The changing speeds throughout the loop tell us the concept of non uniform circular motion.
- A spinning top:
Have you ever played with a spinning top? When you spin a top, it twirls around in circles. But if you watch closely, you’ll notice something interesting. As the top spins, it starts off fast and then slows down gradually. It keeps spinning at a slower speed until it eventually comes to a stop. This changing speed as the top spins is an example of non uniform circular motion. - Frisbee:
When you throw a frisbee, it flies through the air in a curved path. The motion of a frisbee can be an example of a non uniform circular motion. As the frisbee leaves your hand, it accelerates, gaining speed and covering more distance. However, as it moves further away from you, it starts to slow down due to air resistance. This change in speed during its flight demonstrates non-uniform circular motion. - Hula Hooping:
When you hula hoop, you spin the hoop around your waist in a circular motion. But if you pay attention, you’ll notice that the hoop doesn’t spin at the same speed all the time. Sometimes it spins faster, other times it slows down. This changing speed of the hoop, as it goes around, demonstrates non-uniform circular motion. It’s like the hoop has a mind of its own, speeding up and slowing down as it keeps going in circles. - Pulley for gathering water:
A pulley for gathering water is a mechanism that uses a system of ropes and a wheel to lift or lower a bucket in order to collect water from a well or another source. The pulley allows for easier lifting by reducing the effort required. As the pulley is operated, the bucket moves up or down in a circular path. This motion of the pulley represents an example of non-uniform circular motion. - Beyblades:
The Beyblade is a nostalgic childhood toy that many of us have enjoyed playing with.
For those who don’t know, Beyblade is a cool spinning toy that you can battle with. When you launch a Beyblade into the arena, it spins really fast and moves in circles. But if you watch closely, you’ll notice that it doesn’t spin at the same speed all the time. Sometimes it goes faster, sometimes slower. This changing speed and movement of the Beyblade is called non-uniform circular motion.
