 The kind of motion described as from one place to another is called LINEAR MOTION A person running is an example of __ motion. LINEAR The kind of motion that repeats is called HARMONIC MOTION A person swinging on a swing is an example of __ motion. HARMONIC The building blocks of harmonic motion are CYCLES A repeating unit of motion is called a(n) CYCLE How do you find the cycle of a pendulum? FROM STARTING POINT TO RETURN TO STARTING POINT A system showing harmonic motion is called a(n) OSCILLATOR An oscillating system in astronomy is THE SOLAR SYSTEM (orbits) An oscillating system in music is SOUND, MUSIC/BEATS, SPEAKERS An oscillating system in art is COLOR An oscillating system in technology is CELL PHONES, RADIO, CLOCKS The time it takes for one cycle to occur is a(n) PERIOD The symbol for period is T The units for period is SECONDS (s) The equation for period is T = 1/f The number of cycles per second is the FREQUENCY The symbol for frequency is f The unit for frequency is HERTZ (Hz) Another way to write the unit Hz is 1/s The equation for frequency is f= 1/T 0.8 Hz is an example of FREQUENCY 1.25 s is an example of PERIOD 2/s is an example of FREQUENCY How long a cycle lasts is the PERIOD The size of a cycle is AMPLITUDE The maximum distance from the center or average is the AMPLITUDE What is the affect of friction on the motion of a pendulum? SLOWS THE MOTION What is the affect of friction on amplitude? REDUCED (damping) The gradual loss of amplitude of an oscillator is called DAMPING Period and frequency have a(n) __ relationship. INVERSE As the period increases, frequency... DECREASES Which factor(s) affect(s) the length of the period of a pendulum: amplitude, mass, string length? STRING LENGTH (not amplitude due to speed canceling distance; not mass due to acceleration due to gravity being constant for all masses) Which factor(s) affect(s) the length of the time for damping to occur with a pendulum: mass, string length? MASS (because of momentum/inertia) and STRING LENGTH
