How an object vibrates is its
NATURAL FREQUENCY
How can you change the natural frequency?
CHANGE TENSION, LENGTH, WEIGHT, etc.
The oscillation force of a jump rope is
THE PERSON SWINGING THE ROPE
The oscillator response of a jump rope is
THE ROPE MOVING UP AND DOWN
A wave trapped in one spot is a
STANDING WAVE
Frequencies that are multiples of the fundamental are
HARMONICS

INTERFERENCE
If two wave pulses are crests they will __ when they meet.
ADD TOGETHER (MAKE A LARGER CREST WAVE PULSE)
If a crest wave pulse meets a trough wave pulse they will __ when the meet.
CANCEL OUT (MAKE A SMALLER OR NO WAVE PULSE)
If wave pulses add together when they meet, this is called __ interference.
