Only A and B please :)
The equation mgy for gravitational potential energy is valid only for objects near the surface of a planet. Consider two very large objects of mass m_1 and m_2, such as stars or planets, whose centers are separated by the large distance r. These two large objects exert gravitational forces on each other. The gravitational potential energy is U = -Gm_1 m_2/r where G = 6.67 times 10^-11 Nm^2/kg^2 is the gravitational constant. (a) Sketch...

a) By what amount does the mechanical energy of the yo-yo change
after 6.0 s? Answer in units of J.

1- For a uniform electric field, how is the electric potential energy similar to the gravitational potential energy in a uniform gravitational? 2-If a positive charge and a negative charge moving the same way in an electric field have the same change in electric potential energy? 3-For a positive charge moving in an electric field, which direction of motion will cause the electric potential energy to increase? Decrease? Stay constant? 4-How would the answers to the previous question be different...

At the spring meeting of the American Potential Energy Society, a debate erupts over the choice of a reference point for elastic potential energy. One faction (group #1) feels it is only natural to choose the reference point at the location at which the spring is neither stretched nor compressed and to measure the elastic potential energy relative to that unstrained configuration. Another faction (group #2), whose members always like to think "outside of the box", wants to choose the...

Graph the potential energy function (with respect to
x), U(x), of your oscillator and use this to give a physical
explanation of your observation. U(x) can be directly obtained from
the equation of motion (eq (9)). Show clear working for how you
derive this.
