Comparison of Stopping Distance and Time for Two Vehicles

Comparison of Stopping Distance and Time for Two Vehicles When the body is moving with a certain velocity and suddenly brakes are applied, then the body stops completely after covering a certain distance, this is called as Stopping Distance. It is the distance travelled between the time when the body decides to stop a moving Read more about Comparison of Stopping Distance and Time for Two Vehicles[…]

Equation of a Plane Progressive Wave

Equation of a Plane Progressive Wave

Equation of a Plane Progressive Wave 1) If during propagation of a progressive wave, the particles of the medium perform Simple Harmonic Motion about their mean position, then the waves is known as a Harmonic progressive wave. 2) Suppose a plane simple harmonic wave travels from the origin along the positive direction of x – Read more about Equation of a Plane Progressive Wave[…]

Relation between Electric Field and Potential

Relation between Electric Field and Potential The electric filed exists only if there is an electric potential difference. If the charge is uniform at all point, however high the electric potential is, there will not be any electric field. If the field is directed from lower potential to higher then the direction is taken to Read more about Relation between Electric Field and Potential[…]

Displacement in Simple Harmonic Motion

Displacement in Simple Harmonic Motion

Displacement in Simple Harmonic Motion (1) The displacement of a particle executing Simple Harmonic Motion at an instant is defined as the distance of particle from the mean position at that instant. (2) Simple harmonic Motion is also defined as the projection of uniform circular motion of any diameter of circle of reference. (3) If Read more about Displacement in Simple Harmonic Motion[…]

Acceleration in Simple Harmonic Motion (1)

Acceleration in Simple Harmonic Motion

Acceleration in Simple Harmonic Motion Simple Harmonic Motion is any motion where a restoring force is applied that is proportional to the displacement and in the opposite direction of that displacement. (1) The acceleration of the particle executing S.H.M at any instant is defined as the rate of change of its velocity at that instant Read more about Acceleration in Simple Harmonic Motion[…]

Magnetic Maps and Neutral Points

Magnetic Maps and Neutral Points Magnetic Maps: Magnetic map is obtained by drawing lines on the surface of earth, which passes through different places having same magnetic elements. Magnetic maps i.e.., declination, dip and horizontal component over the earth vary in magnitude from place to place. It is found that many places have the same Read more about Magnetic Maps and Neutral Points[…]

Resultant Amplitude and Intensity

Resultant Amplitude and Intensity

Resultant Amplitude and Intensity Intensity if the power transferred per unit area that is perpendicular to the direction of propagation of the energy. Intensity is directly proportional to square root of the amplitude. So, if intensity becomes double, then amplitude will become four times. Let us consider two waves that have the same frequency but Read more about Resultant Amplitude and Intensity[…]
