Angular Displacement Angular displacement is the angle in radians through which a point or line has been rotated in a specified sense about a specified axis. It is the angle of the movement of a body in a circular path. It is the difference between the initial and final angular position of a moving body. Read more about Angular Displacement[…]
NPN – Transistor A transistor is a semiconductor device which is used to switch or amplify electronic signals and electric power. It consists of semiconductor material mostly with at least three terminals for connection to an external circuit. In all the fields of electronics, transistors are used for almost all practical purposes. A semiconductor is mainly used to Read more about NPN – Transistor[…]
Heat Heat flows from the body at higher temperature to the one at lower temperature. The flow stops when the temperature will be equal and the two bodies are then in thermal equilibrium. Heat is energy that flows between a system and its environment by virtue of a temperature difference between them. Heat is a Read more about Heat[…]
Electromotive Force The Electromotive Force is the measure of the energy supply to each coulomb of charge. The EMF is generated by the electrochemical cell, dynamo, photodiodes etc. What is Electromotive Force? Electromotive Force is a measurement of the energy that causes current to flow through a circuit. It can also be defined as the Read more about Electromotive Force[…]
Density Density is a fundamental concept in physics, it is essentially, a measurement of how tightly matter is crammed together. The principle of density was discovered by the Greek Scientist Archimedes. What is Density? The density of a material shows the denseness of that material in a specific given are. This is taken as mass Read more about Density[…]
Electric Charge Electric charge is the property of sub-atomic particles particularly includes electrons and protons. Electrons have negative charge, protons have positive charge and neutrons do not have any charge. Or it is a physical property of matter which causes the force when places in any electromagnetic field. What is Electric Charge? Electric Charge is Read more about Electric Charge[…]
Spring Constant Spring constant is a measure of the elasticity of the spring, it is also known as force constant. The higher its value, the more the force we will need to exert to extend the spring. The quantity that specifies the stiffness of a spring is called as the spring constant. Every spring has Read more about Spring Constant[…]
Force A variety of forces are investigating to show that forces can change either with the shape of an object or its motion. Both balanced and unbalanced forces. What is a Force? Force is defined as the pull or push which produces or tends to produce, destroys or tends to destroy motion in a body, Read more about Force[…]
Uniform & Non – Uniform Motion If we observe our motion from one place to some other place, we can visualize that we are not moving with a constant velocity all the time. Sometimes we are moving at a higher velocity, while at other times like in crowded places the velocity will be less. But we can always Read more about Uniform & Non – Uniform Motion[…]
Electric Field The force felt by a unit positive charge or test charge when its kept near a charge is called Electric Field. It is also defined as the region which attracts or repels a charge. The electric field is a vector quantity and it is denoted by E. the standard units of the electric Read more about Electric Field[…]
