Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time. View a Free Body Diagram of all the forces (including gravitational and normal forces).
Start a chain reaction, or introduce non-radioactive isotopes to prevent one. Watch alpha particles escape from a Polonium nucleus, causing radioactive alpha decay. Control energy production in a nuclear reactor!
