    Modulus is a constant of elasticity given by Hooke's Law, which says stress is directly proportional to strain, within the elastic limit. Modulus of rigidity is one among three elastic constants. It's associated with change in shape of the body. Like every modulus it's too equivalent to the ratio of stress and strain. But as per definition, since it's the modulus of change in shape, therefore, it's precisely expressed by the ratio of shearing stress and shearing strain. We know shearing stress is F÷A and shearing strain is theta ( I would like to consider it β)

    Stress is defined as the force per unit area of a material. Stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other.

    Stress is defined as the force per unit area of a material.
    i.e. Stress = force / cross sectional area

    where, σ = stress, F = force applied, and A= cross sectional area of the object.

    Units of s : Nm-2 or Pa.

    Kepler's Laws Johannes Kepler, working with data painstakingly collected by Tycho Brahe without the aid of a telescope, developed three laws which described the motion of the planets across the sky. 1. The Law of Orbits: All planets move in elliptical orbits, with the sun at one focus. 2. The Law of Areas: A line that connects a planet to the sun sweeps out equal areas in equal times. 3. The Law of Periods: The square of the period of any planet is proportional to the cube of the semimajor axis of its orbit. Kepler's laws were derived for orbits around the sun, but they apply to satellite orbits as well.

    Bernoulli’s theorem: whenever there is an increase in the speed of the liquid, there is a simultaneous decrease in the potential energy of the fluid or we can say that there is a decrease in the pressure of the fluid. Basically, it is a principle of conservation of energy in the case of ideal fluids. If the fluid flows horizontally such that there is no change in the gravitational potential energy of the fluid then increase in velocity of the fluid results in a decrease in pressure of the fluid and vice versa.
