    Perpendicular axes theorem: Moment of inertia is about perpendicular axis in the plane lamina is equal to the sum of moment of inertia is about mutually perpendicular axis. Parallel axis theorem:-moment of inertia of a rigid body about any axis is equal to the sum of moment of inertia about axes passing through centre of mass +product of mass &square of perpendicular distance b/w parallel axis.

    Newton’s third law of motion states that every action has an equal and opposite reaction. This indicates that forces always act in pairs. Reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don’t cancel each other out.

    Hooke's law states that the force F needed to extend or compress a spring by some distance x is proportional to that distance. That is: F= kx where k is a constant factor characteristic of the spring, its stiffness.

    Bernoulli’s Principle

    • For a streamline fluid flow, the sum of the pressure (P), the kinetic energy per unit volume (ρv2/2) and the potential energy per unit volume (ρgh) remain constant.
    • Mathematically:- P+ ρv2/2 + ρgh = constant
      • where P= pressure ,
      • E./ Volume=1/2mv2/V = 1/2v2(m/V) = 1/2ρv2
      • E./Volume = mgh/V = (m/V)gh = ρgh
