Introduction - The word force in common usage refers to a push or pull. The word Mass is also just as familiar as the word force. A super tanker is one that contains an enormous amount of mass. In comparison a coin does not contain much mass. During the seventeenth cen..

But, (acceleration) Hence, Therefore, F = Kma, where K is the constant of proportionality. It we choose the unit of force in such a way that it produces unit acceleration on unit mass, then 1 = K x 1 x 1 Therefore, K = 1 Therefore, F = ma Like velocity and acceleration, force is also a vector quant..

The restoring force in a spring (or in general, any elastic body) obeys Hooke's law. An English scientist Robert Hooke, in the year 1679, enunciated the fundamental law of elasticity in the form ut tensio sic vis which means, As the tension, so is the extension. Within the elastic limits, the defor..

In the physical world, one of the most common phenomena is motion. The branch of Physics, which deals with the behaviour of moving objects, is known as mechanics. Mechanics is further divided into two sections namely Kinematics and Dynamics. Kinematics deals with the study of m..
