    Optimizing Lever Arm Length and Material for Maximum Distance in a Mousetrap Car

    Well, I don't *think* it really matters, as long as it's stable and not too heavy. :smile:

    Optimizing Lever Arm Length and Material for Maximum Distance in a Mousetrap Car

    Well, I have made a mousetrap car not too long ago so hopefully I can help. :smile: However, mine was very different from the rest of the cars, but it went 3m. My friend's mousetrap car got the first place (almost 100m!) and his lever arm was very long. Also, I think he used a fishing rod...

    Electricity Circuit Analysis: Finding Voltage, Current, and Resistance Values

    Hi, I have made a thread about electricity a couple of days ago, which Jimmy kindly helped me out with, but I am again, stuck on the last question (most dificult question). Here is the diagram that I have scanned: http://gallery.cybertarp.com/albums/userpics/12541/electricity2.gif...

    Solving an Electricity Question: Circuit Analysis for V, I, and R Values"

    Hi, I need help with an electricity question where it requires for me to see the circuit diagram and figure out: volage drop across the resistor (V), current flowing through the resistor (I), the resistance constant (R). Here is the link to the diagram that I've scanned...

    Bycicle riding - What power is required at the pedals

    The power required at the pedals of these cycles at any speed on a level, smooth, hard surface, in still air can be expressed as: W = Cv [K1 + K2 (Cv + Cw) ©÷ + 10.32 ¥Òm (s/100 + 1.01a/g)] I found this equation, but I don't get what K1 and K2 is Cw ¡æ speed of headwind in m/s ¥Òm ¡æ...

    How Can Bicycle Mechanics Enhance Your Understanding of Physics in Grade 11?

    I did some reasearch on gyroscopic forces/angular momentum, but I still don't really understand (never touched upon this kind of thing before). The angular momentum is when the bicycle's wheels are spinning, it helps keep the bicycle upright. For example, when the bicycle is leaning to the...

    The Speed of Light: A Constant Mystery

    This might be a bit off-topic, but... Is light a particle or a wave?

    How Can Bicycle Mechanics Enhance Your Understanding of Physics in Grade 11?

    Hello, I just found this place and I am glad I did. :D I have a big physics project and I need to relate bicycle to physics. I am in grade 11 and I was wondering if anybody can give me some ideas/suggestions on what kind of things I can relate physics to bicycle using up to grade 11 physics...
