Gravitational Force
Give this one a try later!
-responsible for attractions btwn objects that have mass
-F- M1M2/ r^2
-require 2 or more objects
always attractive
, Thomsons experiment showed...

-particles could be deflected by electrical fields in a direction that would
indicate - charge
JJ Thomson

-discovered electron
-Cathode ray tube- glass tube consisting of 2 electrodes under very low
pressure, when high voltage is applied cathode emits particles that move
towards anode
Neutrons discovered later...
Give this one a try later!
harder to detect, reside in nucleus, slightly heavier than protons
Scientific Models help us...
