A Short Note on Velocity

“Definition of velocity” is referred to as the length travelled by a distinct object or body per time unit. The difference between “Definition of velocity” and “Definition of speed” has a thin line. Often velocity is also termed speed but velocity is known as vector quantity whereas speed is termed as a scalar quantity. Velocity is extremely important in daily life as it helps in demonstrating the direction and rate of the movement of an object. Consider the instance of a speedometer of a car where it reflects the enormity and not the route of the instantaneous car velocity. In understanding the continuous velocity, an object must possess a regular speed in a continuous and spontaneous direction. It is obtained from the facts and definition of velocity that it is classified into two types, which include “uniform velocity” and “non-uniform velocity”. 

Definition of velocity

“Definition of velocity” mentioned that velocity has an enormity. The standard velocity enormity unit is demonstrated as m/s (metre per second). From the “Definition of velocity”, it is demonstrated that velocity or speed can be calculated directly utilising a flow meter. Velocity is demonstrated as speeding in a particular direction where body direction is mentioned to be accelerating. “Initial and final velocity” illustrates how rapidly an object or a boy moves when the application of force by gravity is on the object. On the contrary, the final velocity is defined as the vector quantity that calculates the direction and speed of a moving body after it has extended to the maximum acceleration. Constant velocity is also important to comprehend from the “definition of velocity” which oversees the spontaneous motion whenever the object slides over low friction and horizontal surface. The dimension obtained from the velocity unit is LT-1.

Concept of uniform velocity

• Uniform velocity is defined as the phenomenon in which the object covers an equal length in the same time interval. (d = v t) demonstrates an equation where v is termed as the average velocity of the object during “time” (t).
• A Uniform velocity graph represents a direct line that is parallel to the “X-axis” when consideration of velocity along the “y-axis” and time is obtained along the “X-axis”. The uniform rate in physics states if the speed of an object is maximising where the “acceleration rate” is continuous.
• Body acceleration operates with the uniform velocity, which is calculated as zero because of no transformation in velocity. Uniform velocity is utilised because of the phenomenon in which the objects fully cover similar distances within time.
• An instance of uniform velocity states that a car is operating on a straight road without any zigzag motion with continuous speed has the “uniform velocity”. The movement of cars in a straight path mainly demonstrates the uniform velocity.
• It is mentioned that if the motion is not persistent in the rectilinear motion case, the object acceleration is mentioned as “non-zero”.

Facts of non-uniform velocity

• “Non-uniform velocity” is defined as when a body does not cover an equal length in the same time intervals in a particularised direction. It is said that if the motion direction transfigures, it is said to be operating with a variable or non-uniform velocity.
• “Non-uniform velocity” has two probabilities: “circle radius is constant” and “centripetal force” is “persistent”. The angular velocity in either case of the non-uniform motion of the circle demonstrates that it is not spontaneous and persistent.
• The formula for non-uniform velocity defines “ω = vr” where “v” varies. Non-uniform motion velocity or motion happens when an object proceeds at a distinct length in intervals of similar time.

Conclusion

Velocity is also termed speed, which is the basic indicator of the position along with the object’s rapidity. From the definition and facts, it is understood that “transfiguration of velocity” indicates the facts of acceleration. Demonstrating the facts of velocity, direction and magnitude are required effectively. Vector quantities are not possible to be added algebraically due to the length with the magnitude and enormity cannot be summed algebraically. An instance of a ball thrown is considered where it is calculated that acceleration and velocity maximize. The common equation of particle velocity with the velocity (V) is mentioned as “V= k (yi^ + xj^)” where K is persistent.
