Waves in General
Unit for relative intensity of sound (how loud we perceive sound)
Decibel
Sound waves are a type of _____________ wave.
Longitudinal
What is a push or pull that acts upon an object?
A force.
What type of variable typically goes on the y-axis?
Dependent Variable
What is the energy of motion?
Kinetic Energy
How far a wave oscillates from its resting point.
Amplitude
As a sound wave's amplitude decreases, its intensity ___________ ?
Decreases
The amount of space an object takes up.
What is volume?
1 hertz (Hz)
What is the type of energy stored in an object?
Potential Energy
The number of wavelengths that pass by a point each second.
Frequency
It is created when an object goes faster than the speed of sound.
Sonic Boom
A substance in which solutes dissolve.
Solvent
In the morning, Ms Lindsey needs coffee. The amount of coffee affects Ms Lindsey's alertness. What is the dependent variable in this scenario?
Ms Lindsey's Alertness
What is the force that attracts one object to another?
Gravity
This type of wave carries light.
Transverse Wave
Perception of how high or low a sound is.
Pitch
Measures the mass of an object compared to its volume. So, how much 'stuff' is in a certain volume.
In a study looking at the effect of exercise duration on heart rate, researchers found the longer someone exercises the higher their heart rate. What is the independent variable in this situation?
Exercise Duration
What is the energy stored within a magnetic field, which is created by the movement of electric charges or magnetic materials?
Magnetic Energy
If a wave travels 24 meters in 4 seconds, what is the wave's speed?
6 m/s
An increase in amplitude when an object vibrating at its natural frequency absorbs energy from a different object vibrating at the same frequency.
Resonance
The speed of sound.
What is 343 m/s?
Inverse Relationship
The force that occurs between two charged objects.
Electrostatic Force
