  • How to Calculate Force from Impulse and Momentum - dummies

    In physics, you can use the impulse-momentum theorem to calculate force based on impulse and momentum. For example, you can relate the impulse with which you hit an object to its consequent change in momentum. According to the theorem: How about using the equation the next time you hit a pool ball? You line up [.]

    Lever The lever arm consists of a lever (rigid rod) and a fulcrum (where the center of rotation occurs). The torque is the same at all positions of the lever arm (both on the same side and on the other side of the fulcrum). If you apply a force at a long distance from the fulcrum, you exert a greater force on a position closer to the fulcrum.

  • What levers does your body use? — Science Learning Hub

    The pivot is the place where your skull meets the top of your spine. Your skull is the lever arm and the neck muscles at the back of the skull provide the force (effort) to lift your head up against the weight of the head (load). When the neck muscles relax, your head nods forward. For this lever, the pivot lies between the effort and load.

  • Escapement - Wikipedia

    An escapement is a mechanical linkage in mechanical watches and clocks that gives impulses to the timekeeping element and periodically releases the gear train to move forward, advancing the clock's hands. The impulse action transfers energy to the clock's timekeeping element (usually a pendulum or balance wheel) to replace the energy lost to friction during its cycle and keep the timekeeper .
