    Relationship between the angle and time of a tilted falling object

    As in my attached pic in OP, θ is between 0 to Pi/2, but I think solving this need more advance mathematical method, which I don't have a clue :confused: Hope someone with the skills and knowledge jump in and give me a hand

    Relationship between the angle and time of a tilted falling object

    Thanks Villyer, for all your help :smile: this should be the last equation now? mgh=mgh(1-sinθ)+0.5Iω2, I=1/3mL2 mgh=mgh(1-sinθ)+(1/2)(1/3)m(2h)2ω2, ω=dθ/dt g=g(1-sinθ)+(2/3)hω2, ω=dθ/dt g=g(1-sinθ)+(2/3)h(dθ/dt)2

    Relationship between the angle and time of a tilted falling object

    sorry about the added m into the term for rotational kinetic energy, it's a typo. as of the moment of inertia I=1/3mL2, assuming m is the mass, L is the length of the object, so the new equation is: mgh=mgh(1-sinθ)+0.5Iω2, I=1/3mL2 mgh=mgh(1-sinθ)+(1/2)(1/3)m(2h)2ω2, ω=θ/t...

    Relationship between the angle and time of a tilted falling object

    that makes sense, so how do I fix the formula? from wikipedia, I found rotational kinetic energy is E=0.5Iω2, so the new formula is something like: mgh=mgh(1-sin(θ))+0.5mIω2 and it can be simplied as: gh=gh(1-sin(θ))+0.5Iω2 Is this one valid now? if it is valid, can you help me...

    Relationship between the angle and time of a tilted falling object

    that's part of the question, the answer is from analyzing the situation, that's the part that I am not sure if my equation is valid.

    Relationship between the angle and time of a tilted falling object

    the object is simply fall on the floor, from almost up right, due to gravity. there is no other force. image you try to put a stick up right on the floor, it simply can't stay up right from the moment you take your hand off it. please ask if i am not making sense, as I am not sure if i...
