what is an atom

It is the smallest unit that matter can be to have an identity

500

How does mass and distance affect gravity?

Gravitational force is larger between objects that are close together and smaller between objects that are farther apart.

500
How do you measure density?
Density is an objects mass divided by volume
500
What could cause discrepant data or experimental errors?
mismeasuring, lack of control, mislabeling
500
There is a big heavy box on the ground, you try to pick it up but you cannot lift it. Use the term "inertia" to explain why.
When inertia is large, there is more mass. Inertia is the tendency of all objects to resist change in motion

What does atomic number and atomic mass measure. Be specific.

atomic number is the number of protons, electrons of an element. atomic mass is protons plus neutrons
