    Undergrad How can you determine if a vector is perpendicular to a plane?

    the way to find out if a vector is perpendicular to a plane the usual way is to find the normal to the plane, then find the cross product of the normal with the vector you are given. if it is 0 then perpendicular, else it is not correct? what i want to know is, can you also, put the the...

    Undergrad Could Non-Linear Length Contraction Resolve Relativity Paradoxes?

    ok so the accepted theory is that the events are not simultaneous, but there is no paradox because everything you observe depends on your frame of reference. (Tell me if I'm correct at this point, call it A) point B, what if, there need not be non-simultaneity if my hypothesis were true...

    Undergrad Could Non-Linear Length Contraction Resolve Relativity Paradoxes?

    hey forum, first of all, I'm a high school kid so forgive me if this is stupid. I've been thinking about relativity for some time now, and the issue with simultaneity. Einstein proposed that length contracts as you approach the speed of light. Assume for a second that a train is going...

    Finding the Center of Mass of a Wing

    nascentoxygen: well this IS a high school task, where not everyone can even do calculus, so the teacher only expects us to produce work up to a certain standard, if we did not assume that the mass is proportional to area then... things would not be fun for those who can't do much math... thanks...

    Finding the Center of Mass of a Wing

    Homework Statement so we have this engineering assignment (high school final year) where we have to design an airplane wing and one of the tasks is to (graphically, not all of us can even differentiate let alone mathematically derive it) identify the center of mass of the wing... now, i know...
