Newton's First Law | Statement And Its Applications

Statement
Newton's First Law, states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.

Few Applications of Newton's First Law Of Motion Are:

Real Life Applications
  • Consider the use of seat belts in a car. When the car takes a bend or curve, if not for seat belts, we would get thrown away from the car. So seat belts provide a balanced force to make us stable.
  • When the bus or train accelerates, we tend to 'fall backward'. This is because we resist the change by falling back thus maintaining the law of inertia.
More Applications
  • Blood rushes from your head to your feet while quickly stopping when riding on a descending elevator.
  • The head of a hammer can be tightened onto the wooden handle by banging the bottom of the handle against a hard surface.
  • A brick is painlessly broken over the hand of a physics teacher by slamming it with a hammer. (CAUTION: do not attempt this at home!)
  • To dislodge ketchup from the bottom of a ketchup bottle, it is often turned upside down and thrusted downward at high speeds and then abruptly halted
  • Headrests are placed in cars to prevent whiplash injuries during rear-end collisions.
  • While riding a skateboard (or wagon or bicycle), you fly forward off the board when hitting a curb or rock or other object that abruptly halts the motion of the skateboard.

Faraday's Law Of Electromagnetic Induction And Its Applications What Is Electromagnetic Induction Faraday's Law Of Electromagnetic Induction Lenz’s law of Electromagnetic Induction Applications of Electromagnetic Induction What Is Electromagnetic Induction Electromagnetic Induction or Induction is a process in which a conductor is put in a particular position and magnetic field keeps varying or magnetic field is stationary and a conductor is moving. This produces a Voltage or EMF (Electromotive Force) across the electrical conductor. Michael Faraday discovered Law of Induction in 1830. Let us now study the Electromagnetic Induction in detail. Faraday's Law Of Electromagnetic Induction First law: Whenever a conductor is placed in a varying magnetic field, EMF induces and this emf is called an induced emf and if the conductor is a closed circuit than the induced current flows through it. Second Law: The magnitu

But we know that the variation of tempe
