    I Taking Projectile Motion to make Planetary Trajectories

    Well I created an equation but its implicitly defined. I am not sure if the computer would have a problem with this. But I do considering i would like to be able to map this out without the assistance of a computer. Here is what I have gotten so far(linked image), but maybe I am overthinking the...

    I Taking Projectile Motion to make Planetary Trajectories

    Hi all I have been trying to find A set of equations that can allow me to map the movement of a planetary body on a polar coordinate sheet (a 2-D Problem). As well as allow me to find out about information such as the perigee and apogee radaii. So far i have been using Keplers equations and...

    Orbital Potential Energy to find r and phi in terms of t.

    Homework Statement A particle in central force field has the orbit r=cφ^2, c is a constant. Find the potential energy, Find r and phi in terms of t. I get how to find the potential energy and found it to be U=-l^2/mu (2c/r^3+l/2r^2) l is angular momentum and mu is the reduced mass But how do I...

    Loop the Loop with Frictional Work

    No, it gets very weird, I tried to define cos(theta) in terms of x and s(the arclenght of the ramp) to make it solvable (I suppose like a gradient), but then I am left with a Theta somewhere in the equation because I cannot find a way to define x without using hsin(theta) or something like it. I...

    Loop the Loop with Frictional Work

    The question is indeed considering friction throughout the entire loop the loop, and I agree, the Integral gets very messy. This isn't for high school though, college.

    Loop the Loop with Frictional Work

    Question: If the Radius of the loop-the-loop is 10meters, from how high above the ground should the object be dropped in order to successfully complete the loop, with friction? I attempted to solve it, but get the integral of cos(theta)dx, or more properly ds, and i do not know how to...

    Relationship of curl and cross product.

    Hi all, I am very confused on how to define the vector product or cross product in a physical sense. I know the vector product is a psuedovector, and that it is the area of a parallelogram geometrically. However, I know it used used to describe rotation in physics. As with torque, magnetism and...

    Calculating the Nuclear Strong Force?

    For an Ap Physics Homework assignment our teacher had us calculate the Nuclear Strong Force for a Helium nucleus with a diameter of 2 femtometers. However, the intention was to calculate the nuclear strong force by assuming that the nucleus is intact, in such a case the particles would not be...
