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 the joule?
The unit for heat.
|
What is V=IR?

|
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?
