What are 3 contact forces?
Push, pull, friction
what has to be formed for sound to occur?
vibrations. Sound forms in waves that have energy that causes vibrations.
When something collides with another object it causes...
change
evaporation, condensation, precipitation, and run-off are all a part of what?
The water cycle
gravity, magnetism, and electricity are what types of forces? Why?
They are non-contact forces because they do not have to physically touch the other object to move it.
