P3.2- COM and Pendulums

HideShow resource information
Centre of mass
where the mass of an object is THOUGHT TO BE concentrated
1 of 8
A hanging object's COM is
directly below the point of suspension. Called equilibrium
2 of 8
Pendulums
move backwards and forwards but always returns to the middle (equilibrium position)
3 of 8
They move in an
oscillating motion
4 of 8
Time period is..
how long it takes the pendulum to complete one full motion (side to side)
5 of 8
The centre has the highest.... but the lowest....
kinetic energy, GPE
6 of 8
At the highest point of swing it has the highest... but the lowest...
GPE, kinetic energy
7 of 8
Fctors that affect the time period
length of pendulum, the amplitude (masximum displacement) of the swing
