Learning Goal: To be able to interpret potential energy diagrams
and predict the corresponding motion of a particle. Potential
energy diagrams for a particle are useful in predicting the motion
of that particle. These diagrams allow one to determine the
direction of the force acting on the particle at any point, the
points of stable and unstable equilibrium, the particle's kinetic
energy, etc. Consider the potential energy diagram shown. (Figure

Determine values for translational kinetic energy, gravitational potential energy, elastic potential energy, and total energy at 0 m, 0.2 m, and 0.4 m above the release point for a 2 kg object pulled 0.2 m downward from the equilibrium position and released from rest while attached to the end of a vertical spring with k = 50 N/m. Be aware that the spring is stretched at the release position and at the equilibrium position so you will have to use...

Potential Energy and Force A mass m=3.00kg moving along the x-axis is acted on only by a single conservative force. The force has a potential energy function given by U(x)=(1.00J/m3)x3−(9.00J/m2)x2+(15.0J/m)x. It will be useful to graph this function on your calculator or computer. Part A Find the force on the mass as a function of x. (Leave the units out of the coefficients in your expression, and make sure all coefficients have three significant figures).
