RPC LESSON 4

• -STRONG NUCLEAR FORCE

  -WEAK NUCLEAR FORCE

  -ELECTROMAGNETIC FORCE

  -GRAVITATIONAL FORCE

  four fundamental processes of nature
• -Binds the fundamental particles of matter (Nucleons) to form larger particles.

  strong nuclear force
• (strongest fundamental force)

  strong nuclear force
• -Responsible for particle decay.

  -Changing of one type of subatomic particle into another.

  -Critical for the nuclear fusion reactions that power the sun and produce energy.

  weak nuclear force
• -The electric force acts between charged particles whether they're moving or stationary creating a field

  -A magnetic field is created when charged particles move.

  electromagnetic force
• (lorentz force)

  electromagnetic force
• -The most intuitive and familiar of the fundamental forces.

  -It is the attraction between two objects that have mass or energy.

  -Oldest known fundamental force

  gravitational force
• (weakest fundamental force)

  gravitational force
• -Protons are fixed inside the nucleus of an atom and are not free to move.

  -Nearly all discussions of electric charge deal with negative charges

  electrostatics
• An object can be said to be electrified if it has too few or too many electrons

  Electrification
• -The electric field points outward from a positive charge and toward a negative charge.

  -When two similar electric charges are brought close together, their electric fields are in opposite directions which causes repulsion.

  electrostatic laws
• -it is the study of electric charges in motion.

  -Recognized as the phenomena of electricity

  electrodynamics
• Occurs when electric potential (Voltage) is applied to objects then electrons move along that object.

  electric current
• Electrons that flow only in one direction.

  direct current
• Electrons that flow alternately in opposite directions.

  alternating current
• A graph that diagrams the phenomenon of DC and shows how it can be described

  current waveform
• The voltage across the total circuit or any portion of the circuit is equal to the current times the resistance.

  Ohm's Law
• all current elements are connected in a line along the same conductor

  series circuit
• Contains elements that are connected at their ends rather than lying in a line along a conductor

  parallel series circuit
• -Measured in watts (W).

  -Commonly used in household electric appliances such as toasters, blenders, and radios.

  electric power
• what is the formula of electric power

  Power (W) = Voltage (V) x Current (A)
• (what makes up protons and neutrons)

  quarks
• Charges are distributed uniformly at the surface.

  Law of Distribution
• electricity

  electric current (I)
• electric potential

  voltage
• measured in ampere (A)

  electric current
• 1 coulomb is equals to

  6.3 x 10 18 electron charges
• k is equals to

  8.99 x 10 9 n.m2/c2
• electric current flows through -

  conductor
• the flow is prevented by -

  insulators
• A graph that diagrams the phenomenon of DC and shows how it can be described.

  current waveform
• x-axis represents -

  time
• y-axis represents -

  amplitude of the electric current
• -No resistance to electron flow

  -No electric potential required

  -Must be very cold

  superconductor
• -Variable resistance

  -Obeys Ohm’s Law

  -Requires Voltage

  conductor
• -Can be conductive

  -Can be resistive

  -Basis for computer microchips

  semiconductor
• -Does not permit electron flow

  -Extremely high resistance

  -Necessary with high voltage

  insulator
• Measured in watts (W)

  electric power
• study of stationary electric charges
