    Study Notes

    Branch of Physics in Engineering

    • The branch of physics that applies physical principles to engineering and technology is known as Applied Physics.

    SI Unit of Force

    • The SI unit of force is the Newton (N), named after Sir Isaac Newton.
    • It is defined as the force required to accelerate a one-kilogram mass by one meter per second squared.

    Energy of Motion

    • The energy possessed by a body due to its motion is called Kinetic Energy.
    • Kinetic energy can be calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.

    Concept of Work in Physics

    • In physics, work is defined as the energy transferred when a force is applied to an object over a distance.
    • Mathematically, work is calculated as W = Fd cos(θ), where W is work, F is the force applied, d is the distance moved by the object, and θ is the angle between the force and the direction of motion.
