What does Newton's 1st Law State?
An object in motion will stay in motion and an object at rest will stay at rest until an unbalanced force acts upon it.
When you decrease the thermal energy of an water vapor, describe what happens to a substance and how it affects its state of matter.
The water vapor is a gas. As you decrease thermal energy, it condenses into a liquid as water, then it freezes into a solid as an ice cube.
As you increase the wavelength of a wave, how does it affect the frequency of the wave?
It decreases the frequency
