Matter
Volume
How much space something has.
Newton's second law
Force = mass * acceleration
Neutron
Part of the nucleus, no charge.
Ball and stick model
Molecular model with atoms as balls and bonds as sticks.
Kinetic energy
Moving energy.
Mass
How much stuff something has.
A force that opposes movement. Applied by touch.
Nucleus
The solid center of an atom.
Reactants
The stuff a reaction starts with.
Potential energy
Stored energy.
Gas
Atoms fly freely, unattached.
Newton's first law
Inertia. Things at rest stay still and things moving keep going until a force acts upon the object.
Proton
Part of the nucleus, positive charge.
Products
The stuff after a reaction happens.
Thermal energy
Heat energy.
Atoms are stiff and in a grid, unmoving.
Magnetism
A force that attracts or repels some metals. Applied at a distance.
Electron
The outside of the atom, moves, negative charge.
What happens to atoms in a reaction?
They are rearranged, but not created or destroyed.
What energies can be waves?
Sound and light.
Liquid
Atoms touch but can slip around.
Newton's third law
Forces are equal and opposite.
Atomic number
How many protons an atom has, what type of atom it is.
Temperature
The kinetic energy of atoms, how fast they are moving.
