  For physics kinematics.
  
  Will the formula which goes sth like s=at^2 be tested for O lvl physics?
  
  If so, care to explain what it means?
  
  It isnt in my physics textbook, but it may be useful in solving qns right?
  
  Thanks alot!!!!!!

  3 main qns for physics kinematics.
  
  1. v = u + at
  
  2. s = ut + 1/2 at^2
  
  3. v^2 = u^2 + 2as
  
  v = Final Velocity of the object
  u = Initial velocity of the object
  a = acceleration of the object.
  t = time taken.
  s = distance travelled by the object.
  
  These equations are true only if acceleration of the object is constant.
  
  These equations by the way are not tested for O Level Physics. However, it is better for you to know them as they are very easy to use. They are more commonly used in A Levels Physics.

  In A level physics, you are required to derive them I think

  thx ! yup i saw my friend do this for tys. He said this is faster and simpler.
