difference between
how much "stuff" (or matter) is in an object
what is mass
a wave that has motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's direction (surface ripples on the water)
transverse
what are the four states of matter that we studied
cold water
slow movement
an object will not change its motion unless a force acts on it.
1st
how much gravity is acting upon an object
what is weight
A sound wave traveling through air
What is longitudinal
dry ice
solid matter
quick movement
hot water
when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
3rd
basic unit of a chemical element
atom
water
liquid matter
In the second law, the force on an object is equal to its mass times its acceleration.
2nd
a group of atoms bonded together
what are molecules
helium
gas matter
lightning
plasma matter
