- - - - BALANCED FORCES:
        if the forces are balance then the object will remains stationary. if forces are in balance then the cancella each other out and the object behaves as if there is no force at all
        
        UNBALANCED FORCES:
        if the forces acting on an object or unbalanced then the object will change its need. it will begin to move speed up slow down or stop.
  - - - W=MG
        mass and gravity{10h/kg)
        
        HOOKE'S LAW:
        
        x=S.L-O.L
        
        F=K×X
        HOOKE'S constant and stretch
        
        K=N/M
        Newton/meter
        
        force on the spring is equals to stretch of the spring
        
        after reaching in scholastic limit it will immediately turn into plastic which means it will break it is where it will stop obeying HOOKE'S law
        
        F IS DIRECTLY PROPORTIONAL TO X
        
        K: IS THE HOOKS CONSTANT AND INDICATES THE STIFFNESS OF THE SPRING. HENCE THE LARGEST SPRING CONSTANT THE STEP FOR THE SPRING IS
      - F=M×A
      - RESULTANT FORCE: F1-F2
  - - - a=FV-IV/T
      - a=m/s
      - d acceleration which is negative acceleration is also known as retardation
      - ACCELERATION DUE TO FREE FALL:
        
        speed increasing due to the factor of gravity and air-resistance
        
        Distance height=V²=v²+2×10×S
      - TERMINAL VELOCITY
        
        forces are balanced air resistance and weight and at that moment it reaches that Speed the object will stop accelerating and maintain a constant or terminal velocity.
        
        a resistance increases with decreases is the parachute is opened while diving
        
        speed at which the force or drag equals to force of gravity on the object
        
        your velocity decreases until your velocity equals to the new force of the drag
  - - - volume of a rectangle:
        l×w×h
      - Volume of a cylinder: π×r²×h
        
        VOLUME OFTEN IRREGULARLY SHAPED OBJECTAND AND UNIVERSAL VOLUME INDICATOR:
        V1-V2
  - - - sound wave is a mechanical longitudinal wave which requires a material medium for its transmission or propagation.
    - - mechanical wave: required material medium preparation and an example of this would be sound waves waves on water surface or waves on stretched string
      - non mechanical waves are electromagnetic waves they do not require material medium and example of this would be light waves radio waves ultraviolet waves microwaves or X-rays
      - PROGRESSIVE WAVE:
        WAVES WHICH TRAVEL CONTINUOUSLY IN THE SAME DIRECTION IN THE GIVEN MEDIUM WITHOUT CHANGING OF FORM ARE CALLED PROGRESSIVE WAVES FOR SUCH WAVES TO PROPAGATE THROUGH A MATERIAL MEDIUM THE MEDIUM SHOULD.:
        BE ELASTIC AS IN THE MEDIUM SHOULD REGAIN THE ORIGINAL STATE AFTER REMOVAL OF DEFORMING FORCES
        possess inertia the capability of storing energy and transparent in the form of waves (is the tendency of an object to maintain its state of rest or uniform motion until and unless it is acted by an unbalanced force)
        frictional resistance should be negligible
        
        structure of a wave
      - LAWS OF REFLECTION:
        1) ray of incidence is equals to ray of refraction
        2) incident re are an opposite sides of reflection Ray they both lion the opposite sides of the normal
        3) the incident normal and the reflected ray lie in the same plane
        
        WAVES CAN BE CONSIDERED BY THREE PROPERTIES:
        TWO CONSECUTIVE CREST
        TWO CONSECUTIVE TROUGH
        ONE TROUGH AND ONE CRUST
      - REFRACTION OF LIGHT: Refraction of light; when one light ray travels from one optical medium to another it suffers a change of direction at the surface of reparation of two media.
        
        LAW OF REFRACTION:
        
        1 LAW: The incident ray, the normal to the refracting surface at the point of incidence and the refracted ray all lie in the same plane
        
        2 LAW: For a given pair of medium and for light of a given wavelength, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant. (ACCORDING TO SNELL'S LAW)
        
        c= speed of light, v= velocity of light
        
        2nd Formula: Mew= 1/sin of angle then 3×10⁸/sine resultant of the angle
