Impulse A car is travelling at full speed. It crashes into the barrier, because of the negligence of the driver. Here the huge force is applied on the wall by the car in a very little time interval which we term as an impulse. Impulse […]
Heat Rate The heat rate is defined as the total amount of energy required to produce one kilowatt-hour (kWh) of electricity by an electric generator or power plant. The formula of heat rate is Rh = Ws × c × ΔT Where, Rh is heat […]
Formula of Elastic Collision The Elastic Collision formula of momentum is given Where, m1 is the mass of 1st body m2 is the mass of 2nd body u1 is the initial velocity of 1st body u2 is the initial velocity of the second body v1 […]
The amplitude of a wave is the maximum displacement of the particle of the medium from its equilibrium position. It is represented by A. The Amplitude formula can be written as where, y is the displacement of the wave in meters A is the amplitude […]
Relative motion is the motion which is computed on the grounds of motion of an object in contrast to another moving motion. The relative term is not conferring to earth but is basically the velocity of the object taken as static when equated to other moving […]
Mechanical energy is the total amount of kinetic energy and potential energy of an object that is used to do a specific work. Mechanical energy can also be defined as the energy of an element due to its position or motion or both. The potential […]
Momentum of Photon Photon is a type of elementary particle which has a zero rest mass and moves with a speed of light in the vacuum. Einstein explained the momentum (p) of a photon with the given formula. The energy and momentum of a photon […]
What is Thermal ExpansionThermal expansion is the phenomenon observed in solids, liquids, and gases. In this process, an object or body expands on the application of heat (temperature). Thermal expansion defines the tendency of an object to change its dimension either in length, density, area, […]
Hooke’s law states that the force required to extend or compress a spring by some distance is directly proportional to that distance. The stiffness of the spring is a constant factor characteristic. The property of elasticity states that it takes twice the much force to […]
Spring is a tool used daily by many of us and their inertia are frequently neglected by assuming it as massless. It’s an extremely casual activity that a Spring when strained, undergoes displacement when it is compacted it gets compressed and when it is free it […]
Electricity is the flow of charge in a conductor from anode to cathode. Electricity has varied applications. It acts as a tool to provide power to electrical devices. We can say the flow of charge builds up the current, which we call Electricity. To understand […]
The law of universal gravitation states that any two objects in the universe attract each other with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. It’s a general Physics law […]
A Doppler shift is a phenomenon of a change in frequency based on the observer’s point of view. The most common analogy of this is standing on the side of the road and listen to a passing car. As the car approaches, there is a […]
A motion is said to be oscillatory if it is repetitive in which an object repeats the same movement over and over. In the absence of friction, the body can be in oscillation forever. But in reality, the system settles in the state of equilibrium […]
Simply resistivity or Electrical resistivity is the resistance of the flow of current from one end to the other in a material. Electrical resistivity is a simply accessible and informative quantity to describe the material. It is the reciprocal of electrical conductivity. The resistivity is […]
