Difference Between Uniform and Nonuniform Motion

A shift in the coordinates about the group is referred to as movement. The reference body is indeed the object on which the movement is measured. There is no object in nature that is complete – completely at rest.

The route (or path) is the line which the body follows as it moves. Routes can be straight or curved, and movement seems to be either linear or nonlinear depending on the shape of the path.

The much more fundamental motion is linear motion, which is further subdivided into uniform & non-uniform motion.

Uniform vs Nonuniform Motion

The difference between Uniform and Non-Uniform motion is based on many factors and conditions. The main point of distinction between these is the change of speed. In uniform motion speed of movement is steady whereas Nonuniform motion represents the variable speed of an object in the time related to movement.

Uniform vs Nonuniform Motion

The most fundamental mechanical motion is a homogeneous linear movement. It’s a consistent uniform motion of such a matter point in such a single direction, as the name implies.

The speed of linear straight motion determines a movement in body position during a specific time interval.

Accelerated motion or Nonuniform motion is a subfield of kinematics concerned with velocity changes while moving. The instantaneous speed of a material point at a specified point in time or on a given trajectory is defined.

It’s also the average speed during a relatively short time, t. The ratio between velocity change to a period has been defined as acceleration.

What is a Uniform Motion?

A uniform linear movement is the most basic combination of mechanical motion. The title suggests it is a constant-speed uniform motion of a material point in such a straight line.

A shift in the body position within such a given time interval is determined by the speed of linear straight motion.

The fundamental property of a unified linear motion is that the displacement is equivalent to the passed trajectory (range). We have said that a body moves at a constant speed when it travels equal length at equal time intervals.

The distance-time relationship to a linear uniform motion is always constant.

Constant velocity denotes that now the body makes equal movement patterns at equal intervals of time in a straight line, still in the same direction.

The above means that perhaps the distance traveled during the first second is the same as the distance traveled in the second of the motion. In other phrases, the acceleration is 0.

In the particular instance of rotary (circular) motion, all parts of the object keep moving around circles in parallel planes, the centers of which are on the spin axis.

Equations trying to describe the cyclic movement can be deduced from the equation of translational motion by substituting the path s – angle of spinning (rad), velocity c – rotation speed (rad/s), & acceleration a – angular rotational acceleration (rad/s2) for the route s – edge of rotation (rad). For uniform rotation (ω  = const) in this case:

What is Nonuniform Motion?

Accelerated motion is a branch of kinematics that studies shifts in velocity while moving. A velocity of a material point at a specific moment in time or on a given trajectory is defined as its momentary speed.

It is also the average speed for a very brief time interval Δt. Acceleration has been defined as the ratio of velocity change to an interval of time. There is no acceleration if indeed the body remains stationary or moves at a constant speed.

As a result, the acceleration could be expressed as an equation in the following way. The average speed is the ratio of both the body’s total displacement to the size of the time interval.

The mean speed should never be determined by calculating an arithmetic average of the speeds of the various parts of the motion. Nonuniform motions are identified as uniform linear motions when the mean speed is introduced.

A uniformly variable movement can be favorably accelerated (a > 0) or negatively accelerated (a < 0), and it can be moved without initial velocity (v0 = 0) or motion with initial velocity (v0 > 0) guess it depends on the acceleration sign.

A uniformly varying motion has a steady acceleration. The above implies that any change in velocity divided up by time interval will result in the same acceleration value. Constant acceleration denotes a change in speed at equal intervals.

The expression: gives the basic equation for velocity in equally constant acceleration. In the case of variable velocity rotation (positively and negatively accelerated (α <0):

Main Differences Between Uniform and Nonuniform Motion

  1. The speed of an object is steady in uniform motion whereas it is variable in the case of nonuniform motion.
  2. Acceleration is zero in uniform motion whereas it can be zero, positive or negative when non-uniform motion is considered.
  3. Uniform motion is always in the same direction but nonuniform motion also changes direction with time.
  4. Distance covered in a specific amount of time is the same in uniform motion whereas nonuniform motion represents a different amount of distance at the same time.
  5. A graph that represents uniform motion is always a straight line in uniform motion whereas it changes its representation to curve when it represents nonuniform motion.
