    Elizabeth Richard   Posted on 2 months ago

    displacement is the distance of a body from one point to another point in specific direction

    Kelvin Kimei   Posted on 3 months ago

    displacement means distance moved in specific direction

    Joel Tweve   Posted on 3 months ago

    is a distance which is covered per particular dirrection

    DOCKHAM JOB   Posted on 3 months ago

    Desplacement is the distance covered in a particular direction.

    Better education

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

    Kelvin Kimei   Posted on 3 months ago

    its true

    DOCKHAM JOB   Posted on 3 months 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.

    WHY efficiency of machine is less than 100%  ??

    Abel Chaplin   Posted on 2 months ago

    Efficiency of a machine is always less than 100 because some energy is changed into other form of energy example in a bulb we decide to get light energy but there is also heat energy so heat reduces the efficiency of light energy to be less than 100

    Johnathan Jonathan Donald   Posted on 3 months ago

    No friction

    DOCKHAM JOB   Posted on 3 months 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 4 months ago

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