Description of this force with links to related topics.
Both the electric field and magnetic field can be defined from the Lorentz force law. The electric force is straightforward, being in the direction of the electric field if the charge q is positive, ...
NASA page explaining the forces involved in flight: lift, drag, thrust and weight.
This is a good clear site that covers projectile motion and forces, includes diagrams and animations to help the explanations.
Java Applet showing how to find (graphically) the resultant of 1, 3, 4, or 5 forces.
Three vector forces that can be changed. The resultant vector is calculated and shown by this JAVA applet.
A simple site that contains an online alternative to plotting compass' or iron filings. The applet is very effective at showing both the direction of the force on an electron and its magnitude.
This page describes in detail the four fundamental forces of nature.
This shockwave activity provides a very basic simulation of the force on an airplane wing. Subscription required but with 30 day free trial.
One of the properties of elasticity is that it takes about twice as much force to stretch a spring twice as far. That linear dependence of displacement upon stretching force is called Hooke's law.
