Term
The two definitions of mass are... 

Definition
1. the measure of an object's inertia 2. the amount of matter in an object 


Term
When determining the net force operating on an object, always ______ forces acting in the same direction and ______ forces acting in opposite directions. 

Definition


Term
What is Newton's third law? 

Definition
"Whenever one object exerts a force on another object, the second object exerts an equal and opposite force on the first." 


Term
The two forces described in Newton's third law are called the _______ force and the ______ force. 

Definition


Term
The action and reaction forces always occur _______. 

Definition


Term
What's the equation for momentum when direction is being considered? 

Definition
momentum = mass X velocity 


Term
What are two differences between momentum and inertia? 

Definition
1. momentum applies only to moving objects, while inertia applies to both moving and static objects. 2. momentum depends on mass and velocity, and inertia depends on mass only. 


Term
How much work has been done on an object that has moved but has ended up where it started? 

Definition


Term
State the law of conservation of energy. 

Definition
"Energy cannot be created or destroyed; it may be transformed from one form to another, but the total amount of energy never changes." 


Term
What is the unit of energy, and what is one of these units equivalent to? 

Definition
Joule; one j = one newton x one meter 


Term
What is the wavelength of a wave? 

Definition
It's the distance between the crest of a wave to the next crest 


Term
What is the amplitude of a wave? 

Definition
the amplitude is the distance in a measure of units from the rest position 


Term
What are two different equations that could be used to find the speed of a wave? 

Definition
1. wave speed = wave length / period 2. wave speed = wavelength x frequency 


Term
what is the range of human hearing? 

Definition


Term
What is the speed of sound in air? 

Definition


Term
What type of wave is a sound wave? 

Definition
They are longitudinal waves. The matter through which the sound wave travels compresses and decompresses in the direction of the wave's motion. 


Term
What is the difference between loudness and intensity? 

Definition
Loudness is a sensation and cannot be measured. Intensity depends on the amplitude of a wave and is measured with decibels. 


Term
Describe the behavior of like and unlike charges. 

Definition
Like charges repel and unlike charges attract 


Term
What is electric potential? 

Definition
the amount of electric potential energy per unit charged in a particle. aka voltage 


Term
What is electric potential energy? 

Definition
the energy a particle possesses due to the location in an electric field 


Term
What is the unit of electric potential? 

Definition


Term
What is the unit of electric charge? 

Definition


Term
Write Ohm's Law in all three possible forms. 

Definition
1. current = voltage / resistance 2. voltage = current x resistance 3. resistance = voltage / current 


Term
Describe the differences between series and parallel circuits 

Definition
In a parallel circuit, the same voltage is applied to each device and each device completes the circuit independently of the others. In a series circuit, electric devices are connected in a row so that the same current flows through each voltage.
