    No 11 characteristics ExplainationMethod of moving lawnmover

    - Push the handle

    - Bigger force produced

    Mass of lawnmower

    - Big

    - To increase the stability

    Size of cutter blade

    - Big size of cutter blade

    - Increase the cutting area of cutting

    grass

    The angle between handle and the

    horizontal

    - large

    - Force exerted to the ground bigger

    - Therefore, I choose lawnmover M,

    - because it has push handle, big mass of lawnmower, big size of cutter blade

    and has large angle between handle and horizontal line
