    Momentum, force, energy and impact to break something.

    In this case, the distance is close enough that the numbers he provided be proved inaccurate

    Momentum, force, energy and impact to break something.

    My mistake, I meant 50 N. Okay so Energy is force applied over a certain distance. Since the "certain distance" in this case is the same, we use the equation Work done = Force . Distance Distance is not a factor in the case because we are simply comparing the two forces. Therefore, the...

    System Dynamics: A Qualitative Understanding

    The system has no external energy and the internal energy is balanced (gravity vs spring). If there is no friction or damping, once the mass is stretched, it will keep oscillating forever. Time has no role here, once you begin this oscillating there is no stopping it without an external force...

    Momentum, force, energy and impact to break something.

    Let's say we have a 100 kg bullet moving at 1 m/s and 1 kg bullet moving at 100 m/s shooting at thick glass with the same size and shape. Both have the same momentum (meaning force required to change the direction of the moving object is same). In this case, the force required to bounce back the...

    Wrong Path, need to step back and re-trace

    Hey folks, I am currently studying at Ryerson (Toronto, Canada) in Computer Engineering (BEng) and I am starting my 3rd year in September. Since high school, I have been very interested in astronomy and quantam physics (at least what was taugh) and I always postulated my own theories on how...
