EJMT Abstract

In upper secondary school, the relation between mathematics and physics is often such that the topics in mathematics are selected in order to support the teaching of important topics in physics. Both mathematics and physics can benefit from graphical explorations in areas such as displacement and velocity, projectile motion and sound waves. The article suggests a way of using dynamic graphical explorations in GeoGebra as a way to visualize concepts of motion and velocity and velocity. In physics, we also study the example of projectiles and we can let GeoGebra show the building of a graph of a hammer throw. We can also allow GeoGebra to visualize how noise cancellation earphones work.
