Waves Force Heat Electricity
What is a wave?
A disturbance in matter that carries energy from one place to another.
What is net force?
The overall force acting on an object.
What is heat?
The transfer of thermal energy from one place to another because of difference in temperature.
What is a conductor?
A material in which charge can flow easily.
What is Hertz?
The unit for wave frequency.
When forces are in the same direction you ________.
What is the joule?
The unit for heat.
What is V=IR?
Ohms Law formula.
False
True or False: Water waves are electromagnetic waves.
What is inertia. Objects that are in motion want to stay in motion and objects at rest want to stay at rest unless acted on by an unbalanced force
Newton's First Law
What is temperature?
The measure of how hot or cold an object is compared to a reference point.
Decreases
When you double the distance between two charges this is what happens to the force.
What is the doppler effect?
An apparent change in the frequency of waves, occurring when the source and observer are in motion relative to each other, with the frequency increasing when the source and observer approach each other and decreasing when they move apart.
What is down?
The direction of gravity in the classroom.
What is thermal energy
Total potential and kinetic energy of all the particles in an object.
What is a parallel circuit
Each brach of this type of circuit has its own current
250 Hz
Period of a wave is 1/250 or .004 seconds. What is its frequency?
The speed that a free falling object reaches force of gravity is equal to that of the air resistance.
Define terminal velocity.
What is q=mc(change in temperature)?
Formula for heat.
What is induction?

What is F = k x q1 x q2 / dxd
Coulomb's Law
