Conceptual Question About Simple Motion

  1. Mar 23, 2012 #1
    If an object was thrown horizontally over a cliff, would you expect it to take longer ot hit the ground below than if it was just dropped over? Please explain.

    Many thanks.

    What do you think? What affects the time taken to reach the bottom?

    If we resolve a vector to a 90° component the result is zero. FCos90°=0
    Thus orthogonal vector will not effect each other.

    In your case the horizontal component(throwing horizontally) will not effect anything what the gravity doing to the object(pulling it down). Both orthogonal to each other.

    If your horizontal velocity is very fast it is possible that the object will be in outer space even the dropping height is small.

    This situation is very different depending on whether or not you want to take into account air drag. I suggest viewing this without drag.

    If you dropped the object off the cliff, what force(s) would be affecting it during its flight?

    If you threw the object off the cliff, what force(s) would be affecting it during its flight?
