Homework Help: Coursework - laws?

  1. May 5, 2005 #1
    Hello: I'm new here and I'm actually from the UK, but hey :biggrin:. I'm currently writing a piece of coursework on the motion of a trolley down a slope, and I was just wondering whether there was a law that states that an increase in the height from which an object is dropped positively correlates with the velocity of the object as it falls.

    Thank you!

    an increase in the height from which an object is dropped positively correlates with the final velocity of the object as it falls.

    It has more time to fall, so it will hit at a greater speed. There isnt a law that states this, but it follows from the mechanics of constant acceleration. You might want to note something about air resistance and terminal velocity.
