    how was phy p11

    Anyways I am done with Physics. See you all next year.

    how was phy p11

    I remember it was written: Acceleration decreases as the drag force increases. Wasnt that what was written

    how was phy p11

    I cant remember that very well. Care to elaborate the question? I remember one question about free falling bodies. I chose acceleration decreases

    how was phy p11

    I can remember some. What was answer to that ball being dropped from a metre rule 80 cm above ? It asked what was its kinetic energy after being bounced.

    how was phy p11

    Yep D is correct.
