To deal with a complicated subject like Physics, students must have in-depth knowledge about the concepts of various related topics. In this regard, the study in the form of difference and comparisons play a crucial role. Students can get a clear understanding of a topic and memorise intricate details about them.
As Physics holds multitudinous aspects and an ocean of topics, sub-topics and related concepts, difference and comparisons Articles in Physics can help students get comprehensive knowledge about the subject.
Benefits of Studying Difference and Comparisons Articles in Physics
The benefits of studying difference and comparisons Articles in Physics are numerous. These include,
Students can well understand every bit of that respective topic.
They can answer various short-type and multiple-choice questions efficiently.
They can also retain points easily and can get an overview of that individual topic.
Difference and Comparisons Articles in Physics
Below is a brief discussion on the difference between various topics.
1. Concave and Convex Mirror
A concave mirror is also known as a covering mirror meaning rounded or hollowed like that of the interior of the circle or sphere. A convex mirror is also known as a fisheye or diverging mirror meaning rounded or curved like a circle or sphere's exterior.
The image properties of a concave mirror are real, inverted and enlarged. On the other, the image created by Convex mirror is virtual, erect and diminished.
2. Mass and Weight
Mass refers to the measurement of the amount of matter in a body. Weight refers to the measurement of the amount of force acting on a mass because of the acceleration caused by gravity. Mass is represented as 'M'. Weight is represented as 'W'.
Students can calculate mass by following many ways. One such way is Mass = volume x density. Similarly, the formula of weight can be stated as Weight=Mass x acceleration due to gravity. Mass can remain the same everywhere, no matter what the location is. However, weight varies depending on the location.
3. Velocity and Speed
Speed points to the rate at which an object can reach a certain distance. Velocity Points to the rate at which an item changes its position in a specified direction.
Quantity of Speed is scalar because it consists of magnitude only. On the other hand, the quantity of Velocity is Vector because it constitutes both magnitude and direction. Whereas, the value of Speed can never be zero or negative, Velocity's value can be zero, negative or positive.
3. Heat and Temperature
Whereas Heat indicates the entire energy of every molecular motion within an object, Temperature points to measure the thermal energy, or the average heat of molecules in a substance.
The SI Unit of Heat is Jules. On the other hand, the SI Unit of Temperature is Kelvin. Heat can flow from hot objects to cool objects and the temperature can rise when it is heated and falls when it is cool. The symbol of Heat and Temperature is represented as Q and T, respectively.
4. Circuit Switching and Packet Switching
In the case of Circuit Switching, a circuit is required to be established to ensure data transmission. On the other hand, in Packet Switching, packets containing information need to be processed through a dynamic route.
Circuit Switching follows a uniform path throughout the entire session. Packet Switching does not have a uniform path. For Circuit Switching, a connection is necessary. However, Packet Switching can be formed without a connection.

FAQs on Difference Between Articles in Physics for JEE Main 2024
1. What is the Difference Between Solar and Lunar Eclipse?
Ans. A solar eclipse occurs when the moon comes between the earth and the sun and blocks the sunlight fully or partially. The lunar eclipse occurs when the earth comes between the earth and moon.
Another point of difference between solar and lunar eclipse is their duration. A solar eclipse occurs once in every 1.5 years and remains so for around 5-7 minutes. A lunar eclipse occurs twice a year and persists for about an hour. Individuals can witness the solar eclipse in a handful of places, whereas, the lunar eclipse is visible from multiple places, at the same time. Also, the solar eclipse occurs in the new moon period, a lunar eclipse happens during the full moon phase. A solar eclipse occurs during day time; lunar eclipse occurs during night time.
2. What is the Battery?
Ans. A battery is an electric device where the potential energy is stored as chemical energy and later is converted to electric energy. The essential function of a battery is to store and release energy. It is an active component of a circuit.
The rate of charging and discharging of batteries occurs comparatively at a slower pace due to the conversion of chemical energy to electric energy. As several devices require a constant energy source to ensure a more extended service, batteries are curated to run for a long time and provide a continuous voltage.
3. What Do You Understand by Density and Volume?
Ans. Density and volume are essential concepts in Physics which are related to physical properties and characteristic of matter. Density in Physics describes the total amount of mass contained in an object. Density is measured in kilograms per cubic meter and represented as D. It widely elaborates the relationship between mass and volume. Density is an intensive property.
Volume in Physics refers to the calculation of the amount of a three-dimensional space occupied by an object. Volume is measured in cubic meters and represented as V. Length, width and height are the three components by which the volume's shape is decided. Unlike density, the volume is an extensive property.
