Here are nine motion problems for physics fanatics to solve. Topics are pretty typical: rifles firing bullets, freight train cars colliding, astronauts gliding through space, balls being thrown. Pupils compute recoil speed, combined...

High school physicists demonstrate Bernoulli's Principle by blowing on different items and finding that they do not move in the expected direction! They apply Bernoulli's equation to the flight of an airplane. This well-organized lesson...

Students are introduced to the concept of Energy Conservation with the example of: Tony Hawk seems to defy the conservation of energy as he keeps reaching new heights on each pass on the halk-pipe. Actually, Tony is supplying the extra...

Students are introduced to potential and kinetic energy through the example of a ball being thrown straight up in the air. They are then told that the energy associated with the position of the object is referred to as potential energy....
