    why when efficiency of machine is 100% VEROCITY RATION is equal to the MECHANICAL ADVANTAGE?

    DOCKHAM JOB   Posted on 1 week ago

    If the efficiency of machine is 100%,It means that there is no frictions in moving parts of the system which can cause some of the energy to lost.Hence the mechanical advantage of a machine will be equal to the verocity ratio.

    DOCKHAM JOB   Posted on 1 week ago

    The efficiency of machine is less than 100% because some of the energy is lost in the moving parts of the system in machine.

    Rugema Patrick   Posted on 3 weeks ago

    Because some energy in a machine is changed into another form due to friction

    TERMINOLOGIES USED IN LINEAR MOTION

                    THE FOLLOWING ARE TERMINOLOGIES USED IN LINEAR MOTION


    DISTANCE  is the length of the path taken by an object in motion.

        - The SI unit is length METER
        - Distance is a scalar quantity, thus has MAGNITUDE ONLY
        - It is represented by letter ''d''

    DISPLACEMENT is the distance covered in a specified direction
       - The SI unit is METER
       - Displacement is a vector quantity,thus has both MAGNITUDE and DIRECTION
       - It is represented by letter ''s''

    VELOCITY is the change in displacement per unit time.
       -The SI unit is meters per second( m/s)
       - It is a vector quantity
       - it is represented by letter 'v '


               MATHEMATICALLY.
            Velocity  =    displacement/ time
                    v    =    s/ t
    ACCELERATION is the change in velocity per unit time.
        - The SI unit is Meter per second square (m/s2)
        - It is a vector quantity
        -

            MATHEMATICALLY
         Acceleration  =   change in velocity/ time
                        a   =   change in v/ t

    TYPES OF FRICTION

    FRICTION is a force that opposes motion


                THERE ARE THREE TYPES OF FRICTION FORCE
       
       (i) Limiting friction 
       (ii) Static friction
       (iii) Dynamic friction

    LIMITING FRICTION 

       -Is the friction between surfaces when they are on the point of sliding over each other.

    STATIC FRICTION

      - Is the friction between surfaces which are not moving.

    DYNAMIC FRICTION

      - Is the friction between surfaces moving relative to each other.

                              OTHER TERMINOLOGIES USED IN FRICTION
      
    COEFICIENT OF FRICTION ( M)
         - Is the ratio of limiting friction to the normal reaction.

         - Coeficient of friction is symbolised by capital letter m (M)
         - It has no SI unit because it is a ratio of two forces.

       MATHEMATICALLY:

           COEFICIENT OF FRICTION  =  Limitting friction / normal reaction
                                                 M =  Fr/ Rr

    NB; 

      NORMAL REACTION 
         - Is the force which is equal to the weight of a certain body.
         - It is symbolised by letter R
         - Its SI unit is NEWTON

         (i) v = u + at
         (ii) s = u + 1/2( at x t)
         (iii) (v x v) = (u x u ) + 2as
