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.
