When you throw your brother into a pool, his body pushes away some of the pool water.
Scientists say the water is displaced.
Your brother floats because the water he displaced weighs the same as his body. This project was designed by physics students at Cariboo Hill Secondary School, encouraging active and innovative learning. With Visual Physics, users can learn about specific topics in physics, run interactive simulations, and participate in basic, yet challenging quizzes which can measure one's progression. Visual Physics is supported by any browser, but best viewed with Java Applet, JavaScript, and frame able browsers. The Physics Classroom is an online physics tutorial written for high school physics students.
