  MINAKSHI TRIPATHI minakshi@iitk.ac.in

• OBJECTIVE
  This project aims at demonstrating a few physics experiments and allows the use to input his own initial conditions.The experiments demonstrated are:
  
  
• A.Oscillations in a pendulum.
• B.Linear Collisions
• C.Atwood machine
• D.Kirchoff's Law
  
  This project aims at explaining the simple experiments which also form a part of our daily life. The basic formulae in physics are used to get the results,they are:
  
  
  1.Equation of simple harmonic motion: a=-kx
  2.Time period of oscillation : T=2*pi*(l/g)^1/2
  3. Conservation of momentum : initial momentum=final momentum
  4.Conservation of mechanical energy : initial energy=final energy
  5.Newton's equations of motion : v=u+at
  6.Second law of Motion : F=ma
  7.Ohm's Law : v=IR
  
  
  The project shows graphically how the change in initial conditions affect the final result and hence proves the relation between the various parameters.
  

MOTIVATION
