Presentation transcript:

Oscillations SHM 1 Simple harmonic motion defined Simple harmonic motion is the motion of any system in which the position of an object can be put in the form... The velocity of such an object is given by … Its acceleration is …

Oscillations SHM 2 x Other definitions t A is the amplitude of the motion.  is the angular frequency of the motion.  is the phase of the motion. A graph of x versus t is very instructive.

Oscillations SHM 3 Other definitions The period tells us the amount of time it takes for the object to come back to the same position. It is given by … Frequency tells us how many times the object passes a certain position in one second. It is given by …
