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.
