The Physical Pendulum with Forces model displays the gravitational, normal, and friction forces acting on a mass attached to a pivoted rod. These forces cause the mass to accelerate in the radially and tangentially with respect to pivot. Although gravity is always downward, friction and normal force change direction in order to keep the mass in the same position on the stick.
The Physical Pendulum Forces model was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_mech_newton_PhysicalPendulumForces.jar file will run the program if Java is installed.
Please note that this resource requires at least version 1.5 of Java (JRE).
