  In physics, Newton's three laws of motion are the fundamental laws of classical mechanics. These laws describe the relationship between an object and the forces acting on it and the motion of the object caused by these forces. These rules are as follows.​   First Law: Every object is at rest or moving at constant speed if no external force acts on it.​   Newton's Second Law of Motion : The rate of change of momentum is proportional to the applied force and the change of momentum is in the direction of the applied force.​   Newton's third law of motion: For every action force there is a reaction force of equal magnitude and opposite direction.​

  The earth’s lithosphere is made up of land and the hard crust beneath it. The lithosphere is not homogeneous but is made up of many types of rocks. ​   Resources in the earth’s crust include minerals, ores, mineral oil and other fuels, rocks, water, elements, etc. ​   Minerals and ores Mineral wealth has an important place among natural resources. Minerals are formed by various processes taking place in the environment. ​   The rocks on the earth are mainly made of minerals. These minerals can be obtained by mining. Only a few metals like, for example, gold, silver, copper, platinum and bismuth occur in the free state in nature. ​   A majority of the metals occur in the form of compounds. Minerals that contain a high proportion of metal are called ores. ​

  ·             British scientist Sir Isaac Newton  made a  Disc. ​ ·             One side of it is divided into equal  petals of red, orange, yellow, green,  blue, indigo and  purple   ​ ·             Place the plate on the stand and  rotate it vigorously. At that time  only one white color was seen  instead of seven colors, proving that  sunlight is made up of seven colors.  That's why it is called 'Newton Disc ’. ​ ·             Newton also wrote 'The Optics' on  light. ​

  ·             All bones in our body are not the same shape. Each bone  is different. All the bones together form a skeleton. ​ ·             The skeleton gives shape to the body. ​ ·             Axial skeleton includes skull, spine and rib cage. Human  body has total 206 bones. ​ ·             Bone structure is hard. Bones are not flexible. Bone  structure is mainly composed of two components. Bones  are formed from inorganic substances like calcium  carbonate, calcium phosphate, minerals, salts. ​ ·             Calcium strengthens our bones. ​ ·             There are four types of bones – flat bones, small bones, ...

  Skin is an important and large organ of the body of all  living  beings. ​ Skin is an important sensory organ of our  body. ​ The outer covering of the body is called the  skin ​ Human skin is mainly composed of two layers.  The  uppermost layer is called the epidermis, while the layer  below it is called the endodermis. Under it are the blood  vessels and the nerve network. Below it is the  subcutaneous layer. It works to regulate body temperature.  The outer skin has different layers. ​ Functions of skin – ​ Protecting the inner parts of the body - such as muscles,  bones, organ systems etc. ​ Helping the body retain moisture. ​ To produce Vitamin D. ​ Controlling body temperature by releasing sweat from the  body. ​ Protection from heat, cold. ​

  • Greek scientist Archimedes invented this device.​   • To draw water from the inside of a large ship, he used a circular tube with a rod attached it.​   • When the rod is rotated, the water starts to rise.​   • The device he invented for pumping out water got the name 'Archimedes screw' and was also used in Egypt.​   • Archimedes designed a large stone throwing machine on the same lines as one can throw stones from a sling.​

  Cellular structure is a major characteristic of all living organisms. Cell is the basic structural and functional unit of all living organisms.​   Various Components are present in the cells to carry out the life activities of living organisms. ​   These elements are called organelles.​   Plant cells have a definite shape due to the presence of the cell wall around them. Besides, unlike animal cells, plant cells contain single large vacuole. All these cells are known as eukaryotic cells.​   The nucleus is the most important organelle of the cell. There is a porous double membrane around it. The nucleus controls all functions of the cell. ​   The endoplasmic reticulum is a sprawling net-like organelle. Its function is to make necessary changes in the proteins produced by ribosomes and send them to the Golgi bodies. ​   Golgi bodies are made up of several flat sacs. Their function is the proper distribution of proteins. ​ ...
