Useful Websites
Physics of Kung Fu A multimedia website designed to engage young people. The website follows a young physicist as she learns how to break through three planks of wood. She keeps a lab book of her thoughts and experiments. The website also includes videos of the techniques, discusses the physics principles involved and shows her calculating the energy required and working out whether she can break the wood, given her size and the speed of her arm.Traffic Light system

IT Applications
Applets
There are an increasing number of applets being developed around the world. Some of the developers have written quite a large number across many fields of physics and science in general. Under the “Links” area of this website there is a section for applets where you can select one of the web site of these developers to see the range that they have produced.Listed below are the applets from these developers for this particular Area of Study. Each has a description to give you some idea of its usefulness and relevance. The first name is the developer, the second is the category or section within their site and the third is the applet’s title.
Please read the descriptions below, and then go to the Links section.
- Walter Fendt/Mechanics/Motion with Constant Acceleration
- You set initial values of position, velocity and acceleration for a car moving across the screen. Press Start and the car moves across the screen. Position, vel and accel’n vs time graphs are produced as the car moves. Negative values of vel and accel’n are accepted as well. An arrow on the car can show either the direction of the velocity or the acceleration.
- Walter Fendt/Mechanics/Equilibrium of Three Forces
- A point has three masses attached by cords. One hangs vertically, the other two hang over pulleys. The weight force in Newtons on each can be adjusted. The diagram adjusts automatically to reflect the new situation, and the angles between the forces are also given.
- Walter Fendt/Mechanics /Resultant of Forces (addition of vectors)
- The applet shows the process of adding the forces, one by one, and displays the resultant vector. You can select from 2 to 5 forces and each of the forces can be altered in size and direction.
- Walter Fendt/Mechanics /Inclined Plane
- A mass is pulled up an inclined plane. The angle of the plane, the mass of the object and the value of the coefficient of friction can be adjusted. The parallel and normal components of the weight force, the size of the friction force and the required force to make the object move are shown. After you select “Start” the mass moves up the plane with all the force vectors displayed.
- Walter Fendt/Mechanics/Newton’s Second Law Experiment
- The applet simulates an air track set up. A glider is pulled along by a mass hanging over the end. The masses of the glider and the hanging mass can be adjusted. The coefficient of friction can also be varied. After you select “Start” the combined mass system begins to move. At the same time a point moves along a Disp – Time graph. A Light beam can be placed anywhere along the glider path. When the glider cuts the beam, the time and displacement are measured. A permanent dot is placed on the graph, and the data can be saved, and added to earlier measurements with the light beam in different positions. The effect of the size of the falling mass on the acceleration can also be investigated, as well as the effect of friction.
- Walter Fendt/Oscillations and Waves/The Pendulum
- The display features an oscillating pendulum, but you can choose to show either of the following graphs against time: displacement, velocity, tangential acceleration, net tangential force and energies, GPE and KE. The graphs have a dot moving along them in time with the oscillation. In addition as the pendulum oscillates there is a vector representing the selected quantity on the mass. The force diagram shows the weight, tension and net tangential force. You are able to vary the length, mass and amplitude. There is also a slow motion option. Note: the applet does not use the phrase “tangential force”, just “Force”, whose value goes to zero at the mid point, with the weight force and tension being equal and opposite. The applet would be useful in Year 11 in illustrating the relationships between vel, accel’n and net force, and GPE and KE.
