  1.Does a pendulum with a lighter bob or a heavier bob record a lower period?
  
  2. Suppose we have the pendulum displaced at a lower angle, say 4 degrees instead of 5, how does it affect the period?
  
  3. Does a shorter or longer pendulum affect the oscillation?
  
  4. And lastly, if the pendulum swing happens on the moon instead of the earth, does any change in period result?
  
  Thanks.

  - lower angle more accurate
  3. Does a shorter or longer pendulum affect the oscillation?
  - shorter more accurate
  Thanks.

  herein lies ur answers:
  
  Period = 2 × pi × sqrt (length of pendulum ÷ gravitational acceleration)
