Transcript of Using Physics

Using the text book page 229
find the centre of mass of a piece of card
draw a diagram to explain the method.
Simple Pendulum (diagram)
Amplitude of an oscillating object (equilibrium to highest point)
Time Period (between successive phases)
measure the time period
time 20 complete cycles
divide by 20
Time period = 1/ Frequency of the oscillations (Hz)

T= 1/F
The Pendulum

Using Physics
Finding the centre of mass

Does the time period depend on the amplitude?
plot a graph of time period against amplitude in mm,
Does the time period depend on pendulum length?
Plot a suitable graph
