Position Vector Position vector is a vector which represents the position of a point in a space with respect to the origin. It also represents the distance and direction of the points from the origin. If A is the point then the position vector of A is represented by O is the origin and A Read more about Position Vector[…]
Modulation Modulation is the branch of science in electronics and communication systems including varying the fundamental properties of the basic signal by superimposing it with a carrier signal to carry the signal from one location to the other. Modulation is the process of changing the characteristics of the carrier signal, in accordance with the amplitude Read more about Modulation[…]
Electrostatics Electrostatics plays a major role in everyday life. Electrostatics is a branch of physics in which static electric field produced by static electric charges are studied. The various applications of electrostatics include photocopiers, defibrillator, paint spraying, electrostatic precipitator etc. Electrostatics is used in the agricultural activities like spraying to plants, sorting seeds etc. Electronic Read more about Electrostatics[…]
Displacement Vector Displacement vector is a vector joining the initial position of the particle to its final position after an interval of time. Mathematically, it is equal to the change in position vector. . Where, = Displacement Vector from point A to B. The displacement of the particle would be the vector line AB, headed Read more about Displacement Vector[…]
Electric Dipole An electric dipole is a pair of two objects having equal and opposite charges, separated by a distance d. suppose there are two charges of equal magnitude, separated by a distance d. Assume the first charge be negative and the second charge be positive, this combination is called as an Electric dipole. Therefore, Read more about Electric Dipole[…]
Contact Force Force is defined as that pull or push which produces or tends to produce, destroys or tends to destroy motion in a body, increases or decreases the speed of the body or changes its direction of motion. Therefore, “Force” is an external or internal agent present to “influence” the natural state of motion of Read more about Contact Force[…]
Gravitational Field The space around an object within which its force of gravitation is experienced is termed as gravitational field. What is Gravitational field Intensity? The gravitational field intensity is the intensity of the gravitational field of a material body at any point in its field is defined as the force experienced by a unit mass placed Read more about Gravitational Field[…]
Tension The most important application of Newton’s motion Laws is the explanation of tension. Ropes and strings are very useful in machines and mechanical systems. These are used to push or pull heavy loads. We can see the tension in using of ropes or cables. If we consider a load which is pulled by a rope, a person is Read more about Tension[…]
Degrees of Freedom The degrees of freedom can be calculated to help ensure the statistical validity of t – tests and even the more advanced f – tests. The number of degrees of freedom refers to the difference between the numbers of independent observations in a sample and the number of population parameters that must Read more about Degrees of Freedom[…]
Angular Speed Angular speed is the rate at which an object changes its angle in radians, in a given time period. Angular speed has a magnitude only. Angular Speed (ω) = θ/ t Where, ω = Angular Speed in rad/sec, θ = Angle in radians, t = time in seconds. Angular speed and angular velocity Read more about Angular Speed[…]
