Calculate the speed (in m/s) of an electron and a proton with a
kinetic energy of 1.70 electron volt (eV). (The electron and proton
masses are me = 9.11 ✕ 10−31 kg and mp = 1.67 ✕ 10−27 kg.
Boltzmann's constant is kB = 1.38 ✕ 10−23 J/K.)

b. Compare what happens to potential energy, kinetic energy, and
total energy as the skater moves up and down the track. What
general statement can you make about the relationship between
potential and kinetic energy?
c. Notice that the bar entitled “Thermal” energy does not
deviate from zero. This represents an energy that is transformed
into "heat" energy. What must be true of this skate park for this
to remain at zero?
d. Vary the skater's Mass with the slider...
What do the graphs of kinetic energy and potential
energy look like as the mass moves? What do the graphs of position,
velocity, and acceleration look like?
What is damping and how does it affect this
system?
What’s the difference if the mass on a spring is horizontal
instead of vertical?
What is resonance and when does it
occur?
1. What is the momentum (p) of a 960-MeV proton
(that is, its kinetic energy is 960 MeVMeV )?
Express your answer with the appropriate units.
2. An electron (mmm = 9.11×10−31 kg
