Potential difference equation
V= I X r
V=potential difference
I=current
R=resistance
Potential difference
Voltage - measure in volts
I
Current - measure in amps
R
Resistence - measured in ohms
Internal energy
The kinetic and potential energy added together
Density
Mass/volume=density
Mass- use a balance
Volume - eurka can
Eurka can
Fill the water up to the top. Submerge an object into the can and make sure a measure cylinder is placed underneath. Read the volume of water removed from the eurka can
Uncertainty calculation
The range/2
The range = biggest take smallest
Proton
Positive +1
Neutron
Neautral = 0
Electron
Negative -1
Solid
Tightly packed together in regular pattern
Liquid
Are close together with no arrangement
