 What variable is on the y-axis of a harmonic motion graph? POSITION (cm) What is the variable on the x-axis of a harmonic motion graph? TIME (s) Another name for harmonic motion is PERIODIC MOTION What does the value of y=0 on a harmonic motion graph refer to if showing the motion of a pendulum? CENTER POINT OF MOTION What does a negative y value on a harmonic motion graph refer to if showing the motion of a pendulum? MOTION TO THE LEFT OF CENTER What does a positive y value on a harmonic motion graph refer to if showing the motion of a pendulum? MOTION TO THE RIGHT OF CENTER What does a maximum negative y value on a harmonic motion graph refer to if showing the motion of a pendulum? AMPLITUDE What does a maximum positive y value on a harmonic motion graph refer to if showing the motion of a pendulum? AMPLITUDE What is the equation for calculating amplitude from a harmonic motion graph? 1/2(HIGH-LOW) What are the units for amplitude? usually CENTIMETERS or METERS What is the equation for calculating period from a harmonic motion graph? END TIME - START TIME The point of the oscillator within a cycle is the PHASE The common unit of measurement for a phase is DEGREES One rotation is an example of a CYCLE What distinguishes circular motion from harmonic motion? CIRCULAR MOTION ALWAYS LASTS 360 DEGREES What term is used to describe two oscillators with the exact same period that start at the exact same time? IN PHASE When cycles are aligned, the oscillators are said to be IN PHASE What term is used to describe two oscillators with the exact same period that start at different times? OUT OF PHASE Other than different starting times, what other factor can cause two oscillators to be out of phase? DIFFERENT PERIODS 12.25 CYCLES How many cycles are shown? 2 Hz If it takes the oscillation 24.5 seconds to be complete, what is its frequency? 24.5 s If it takes the oscillation 24.5 seconds to be complete, what is its period?
