 Take the pretest- Let’s see what you remember!

 Electromagnetic  Gravity  Strong Force  Weak Force  Forces are not transmitted directly between objects, but instead are described by interactions in force fields.  Each force has an “exchange particle.”

 Interaction of particles with an electrical charge.  For a long time, the electric and magnetic forces were considered to be different forces, but they were finally unified by James Clerk Maxwell in  Electromagnetism is perhaps the most obvious prevalent force in our world, as it can affect things at a reasonable distance and with a fair amount of force…can attract & repel.  The photon is the exchange particle for this force.photon

 Furthest reach, but it's the weakest in actual magnitude.  a long-range attractive force that acts on all particles.  Exchange particle has been named the graviton. graviton

 Keeps nucleons (protons & neutrons) bound together.  Force is at the subatomic level.  The strongest force of all known forces.  Holds quarks together to form neutrons and protons, and holds neutrons and protons together to form nuclei.quarksneutrons protons  The exchange particle is the gluon.gluon

 The weak interaction is a very powerful force that acts on the scale of the atomic nucleus.  It causes radioactive decay and explains nuclear fusion reactions in stars.  A repulsive short-range force.  Exchange particle is the boson (W & Z) and these particles were only confirmed in 1983!

 Modern unified field theory attempts to bring these four interactions together into a single framework.  Electromagnetism, Strong & Weak forces have been unified.  Gravity is not, but physicists are working on that…

 Has to do with electric charge.  Electric charge creates electromagnetic fields that interact.  Studied since ancient times, but only in modern time that we have been able to put it to practical use.  Plenty of examples of well known effects: lightning, static, electric current…

 Charged objects exert a force and within the structure of an atom are different charges that exert forces.  Clip 1- 2 min Overview of Structure of an atom sY sY  Clip 2 –7 min44s The atom, quarks, and elements nM nM
