For example, in earth gravity, a car of 1000 kg on asphalt will need a force of around 100 newtons for rolling (1000 kg × 9.81 m/s2 × 0.01 = 98.1 N).

Famous quotes containing the words rolling, resistance and/or examples:

    “I caught this morning morning’s minion, king-
    dom of daylight’s dauphin, dapple-dawn-drawn Falcon, in his riding
    Of the rolling level underneath him steady air, and striding
    High there, how he rung upon the rein of a wimpling wing
    In his ecstasy!”
    —Gerard Manley Hopkins (1844–1889)

    “How is freedom measured, in individuals as in nations? By the resistance which has to be overcome, by the effort it costs to stay aloft. One would have to seek the highest type of free man where the greatest resistance is constantly being overcome: five steps from tyranny, near the threshold of the danger of servitude.”
    —Friedrich Nietzsche (1844–1900)

    “In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.”
    —Michel de Montaigne (1533–1592)
