G.E.M'S Of PHYSICS

Gravitational Field(G)
- Newton's Law Of Universal Law Of Gravitation
  - Affected By
    - MASS
    - GRAVITATION CONSTANT
    - DISTANCE BETWEEN TWO MASS
- DEFINITION
  - COLLECTION OF VECTORS DETERMINE 2 VALUE OF GRAVITATIONAL FORCES
    - DIRECTION
    - MAGNITUDE
- FIELD STRENGTH
  - Force of attraction per unit of mass in a gravitional field
- SATELITES AND ORBITS
  - ORBITAL RADIUS
    - DISTANCE OF THE CENTRE OF THE SATELITE WITH THE CENTRE OF A PLANET
  - SPEED OF SATELITES
  - TYPES OF ORBITS
    - GEOSYNCHRONOUS
      - ORBIT AROUND EARTH THAT MATCHING EARTH ROTATION
    - GEOSTATIONARY
      - ORBIT REMAIN FIXED ALL THE TIMES
        Used for ommunication purposes like radio and television networks, backhaul, and direct broadcast.
Electric Field(E)
- TYPE OF MATERILAS
  - CONDUCTOR
    - ELECTRON CAN MOVE FROM ONE ATOM TO ANOTHER
    - Thermometer(Mercury)
  - INSULATOR
    - ELECTRON ARE FIXED IN A POSITION
    - Handled of frying pan
- ELECTRIC FORCE
- Electric charge
  - q= amount of charge
  - Unit= Coulomb
- Coulomb Law
  - Charles-Augustin de Coulomb
  - THE FORCE BETWEEN TWO POINT CHARGES IS INVERSELY PROPORTIONAL TO THE SQUARE OF THE DISTANCE BETWEEN THE CHARGES AND DIRECTLY PROPORTIONAL TO THE PRODUCT OF THE CHARGES
- electric field
  - PARALLEL PLATE
    - UNIFORM CHARGE
  - EPSILON
- ELECTRIC DIPOLE
  - OPPOSITE CHARGE WITH CENTER SEPERATE BY SMALL DISTANCE
- ELECTRIC POTENTIAL (v)
  - POTENTIAL ENERGY PER UNIT OF CHARGE A GIVEN POINT
  - 1V=1J/C=1 N.M/C
- ELECTRIC POTENTIAL ENERGY
  - ENERGY STORED IN A SYSTEM CONSISTS OF 2 CHARGES
  - ELECTRIC ENERGY STORED IN AN ELECTRIC FIELD THAT CAN DO WORK
MAGNETIC FIELD (M)
- EARTH MAGNETIC FIELD
  - NORTH POLE
    - EXPERIENCED SOUTH POLE MAGNETIC FIELD
  - SOUTH POLE
    - EXPERIENCE NORTH POLE MAGNETIC FIELD
  - Compass used Earth Magnetic field
- ELECTROMAGNET
  - STRAIGHT LINE CONDUCTOR AND SOLENOID
    - RIGHT-HAND RULE
  - MOVING CHARGED IN MAGNETIC FIELD
- MAGNETIC FORCE
  - MOVING CHARGE
    - B(MAGNETIC FIELD) UNIT=TESLA/T
  - CURRENT-CARRYING CONDUCTOR
