1 Star Forces: Question of the day!
What are the main forces controlling the universe? How do forces influence stars? Review!!! 

3 Forces Inside Stars Electric (Electromagnetic) Force
Attraction and repulsion of positive and negative electric charges Stronger than gravitational force Strong Nuclear Force Holds the particles in a nucleus together Strongest force Weak Nuclear Force Causes atomic nuclei to break down Responsible for synthesizing elements in supernova explosions Gravitational Force Attractive force dependent on mass and distance

4 Strong Nuclear Force Holds the particles in a nucleus together Strongest force The strongest of the forces is the strong nuclear force, which is the force that, among other things, keeps protons & neutrons bound together. In the helium atom, for example, it is strong enough to bind two protons together despite the fact that their positive electrical charges cause them to repulse each other.

5 Electric (Electromagnetic) Force
Attraction and repulsion of positive and negative electric charges Stronger than gravitational force Electromagnetism is the interaction of particles with an electrical charge. Charged particles at rest interact through electrostatic forces, while in motion they interact through both electrical and magnetic forces. Electromagnetism is the most obviously prevalent force in our world, as it can affect things at a reasonable distance and with a fair amount of force.

6 Weak Nuclear Force Causes atomic nuclei to break down Responsible for synthesizing elements in supernova explosions The weak interaction is a very powerful force that acts on the scale of the atomic nucleus. It causes phenomena such as radioactive decay.  decay is the process by which an atomic nucleus of an unstable atom emits neutrons which then break down into protons, electrons and other electrically neutral subatomic particles.

7 Gravitational Force Attractive force dependent on mass and distance Gravity has the furthest reach but it's the weakest in actual magnitude. It is a purely attractive force which reaches through even the "empty" void of space to draw two masses toward each other.

which Einstein called the unified field…

10 Back to the original questions!
What are the main forces controlling the universe? How do forces influence stars? Which forces are most important for stars? Why?
