Coulomb’s force is the electrical force between two charges. Since there are positive and negative charges, coulomb’s force can be attractive or repulsive. However, the magnitude of the force produced by a point charge...

Energy changes in according to displacement The kinetic energy of a simple harmonic oscillator is In a SHM, the oscillator’s kinetic energy and potential energy always changes from maximum to zero throughout the oscillations....

Uniform gravitational force The gravitational force acting on a mass is called weight. Weight always acts vertically down and its magnitude is directly proportional to the mass. where g is the gravitational field strength on...
