Define the Concept of Objects Around Us?

When we look all over we are surrounded by so many different types of objects around us. This can include almost anything like books, pens, pencil, fan, bag, television, etc. all these objects around us were invented or discovered by us to fulfil a particular objective or purpose. All these objects have their properties and we need to know them. These properties differ from each other and their use depends mainly on their properties. We observe objects around us due to the presence of light and it has also its properties. Further, we will see how these objects are classified into groups.


How to Identify Objects Based on Different Classifications?

Generally, we observe objects around us that can be identified based on the different classifications. Let us take a look at them. 

  • Colour

The objects having the same colours can be classified into a single cluster. Both colour and appearance help to classify objects into clusters. For example, red has been associated with the symbol of danger or evil. 

  • Texture

The surface material of every object is different and this leads to the classification of objects based on textures. This object cluster is formed with the surface and material of the object. For example, the material with a rough surface includes the sandpaper, whereas the material with a soft surface is the wool, fur, silk, etc. 

  • Lustre

Objects around us that shine and reflect light are classified into the category of lustre. This shiny property leads to the formation of a cluster. For example, the objects used in the making of ornaments like gold, silver, platinum and others. 

  • Opacity

The objects with a property of transparency are classified into a separate cluster known as opacity. Opacity determines the amount of light that passes through an object. For example, shadows are cast from opaque objects through which the light is not able to pass like metal sheets or woods. While objects through which light passes are either transparent or translucent such as glass, water, fibreglass, etc. 

  • Shape

Objects having a similar shape fall under the category of the same cluster. Different geometrical shapes, different shape clusters. For example, a round shape object will include balls, dish, circle, sphere, etc. 

What are the Symmetrical Objects Around Us Like?

The symmetrical objects around us like glass that appears similar from both the right and left side. It generally refers to all those objects that can be split into two identical halves. The objects that cannot be divided into two halves are asymmetrical. A line of symmetry passes through the object mostly through the centre and divides into same halves. For instance, if we fold a paper into a line of symmetry, each part of the paper will overlap the other part. 

What Happens If All Objects Around Us Reflect Light in a Regular Way? 

If all objects around us regularly reflect light, the light would reflect only one direction by all the objects. There will be a single direction through which we can see the objects, the other directions will not show us the object. 

Did You Know?

Objects around us have importance in our daily life and activities surrounding it. With object classification, it will be easier for us to identify them. Moreover, if we know the property of one classified object, it will help us to know the property of the other one belonging to the same group.

FAQs on Objects Around Us

Q1. What are the 3D Shapes Around Us?

Ans: The 3D shapes around us depict the three-dimensional shapes that can be measured in all the three directions. There are three directions- the length, breadth and height of a geometrical figure or shape. 3D shapes are also known as solid shapes. Three-dimensional geometry calculations deal with these 3D figures. The only difference between a 3D shape and 2D shape is the thickness which is present in 3D objects. There are numerous examples of three-dimensional figures that we can notice in our everyday life. This includes a tube, cone, sphere, cylinder, cube, etc. Two distinct measures help to define the 3D shapes in a better way that is volume and surface area. 

Q2. What are the 2D Shapes Around Us?

Ans: In math, the 2D shapes around us are the common geometrical figures and shapes that can be simply drawn on a flat piece of paper. These two-dimensional objects are measured with the help of length and breadth. The properties of every 2D shapes differ from each other. Some include the sides and corners while others have curved surfaces and boundaries. 2D shapes and objects have a common application in chapters of menstruation dealing with area and perimeter of the surfaces. These 2D surfaces typically lack the thickness or height which is found in the 3D objects. Some common examples of 2D shapes are circle, square, rectangle, triangle, rhombus, hexagon, pentagon, and others.
