Non-uniform motion

The study of motion has progressed throughout history and is now an essential aspect of physics. The ideas of speed, distance, and time are the three most significant concepts used to categorise different forms of motion. The motion may be classified into two sorts based on the amount of time and distance travelled that is uniform and non-uniform motion. 

 Non-Uniform motion is defined as the motion when a moving object travels an uneven distance in equal intervals of time, or an equal distance in unequal intervals of time, or an unequal distance in unequal intervals of time.

Non-Uniform Motion is the term used to describe a motion in which an item travels at a variable pace. This signifies that the object does not travel the same distance in the same amount of time as before. In the case of rectilinear motion, the acceleration of the body will be non-zero if the motion is not consistent with the rest of the motion. For example, the general motion of a vehicle in traffic is an example of non-uniform motion. Non-uniform motion is also referred to as rapid motion.

What is non-uniform motion, and how does it work?

Accelerated motion is a type of kinematic motion in which variations in speed occur during a move. The momentary velocity is the particle’s velocity at a particular instant in time or at a specific location along its route. In terms of time interval, it is comparable to the mean speed during a relatively short period. Generally speaking, acceleration is defined as the ratio of the change in velocity to the time required to achieve that change. If the body remains at a single location or moves steadily, it does not experience any acceleration.

A uniformly variable motion may be classified as either positively accelerated (a> 0) or negatively accelerated (a<0). It can also be classified as either motion with no starting speed (u= 0) or motion having an initial speed ( u> 0).

Examples of Non-Uniform Motion

Most of the motions we see around us are non-uniform in their origin. Some of them are as follows:

1.   A horse on the go

2.    A man competing in a 100-meter dash

3.    A soft, bouncy ball

4.   An automobile collision with another automobile

5.    A plane flies through the sky before coming down to land.

6.   A box is being dragged away from a walkway.

7.    A bus makes its way through the market on its route to its destination.

8.   An automobile comes to a complete stop.

9.   A train approaches the station where it will terminate its service.

10.    The motion of an asteroid

Laws of Motion

Quantum mechanics refers to the motion of subatomic particles such as electrons, protons, and so on, whereas classical mechanics refers to the motion of every particle. Sir Isaac Newton introduced the three principles of motion in 1686, laying the groundwork for classical mechanics and allowing for significant advances in the area.

Newton’s First Law

Newton’s first law asserts that a body at rest or in motion will remain at rest or in steady motion until an external force is applied to change its position.

 Law of Force and Acceleration

Newton’s second law outlines the motion of an item and the impact that an external force can have on it. It asserts that the rate of change in acceleration of an object in motion is dependent on the mass of the body and the force applied on that object, with acceleration being directly proportional to the force and inversely proportional to the mass of the object.

F=ma

Newton’s Third Law

Newton’s third law of motion says that for every force applied to an object, there is a reactive force equal in magnitude and opposite in direction to the original force on the object applying it. 

Conclusion

There are two types of motion: uniform motion and non-uniform motion. A body in uniform motion travels the same distance in the same amount of time at the same speed. In uniform motion, there is no acceleration. A body moving in a non-uniform manner travels different lengths and covers different distances at different speeds. Non-uniform motion causes an acceleration that is not zero.

 We are all aware that mobility plays a crucial part in our day-to-day activities. Life would be nearly impossible to live without it. The amount of time it will take for the items to travel the distance is dependent on their size. For example, quick things travel a distance in a shorter amount of time, whereas slow objects travel a distance longer. It is also apparent from the preceding article that the difference between uniform and non-uniform motion is determined by the velocity of the moving body, regardless of whether the velocity is changing or remains unchanged.
