Viewers learn that one of the chief ways in which heat energy moves is in the form of waves. This kind of heat transfer is called radiation.

This program explains how the principle of buoyancy is responsible for the process of heat transfer called convection.

Eureka! looks at the process of conduction, explaining that the application of heat to an object makes the molecules or atoms vibrate faster and cause a sort of "domino effect."

Isaac Newton's celebrated falling apple is cited to explain the force of gravity and the unit with which the force of gravity is measured. Concept: Force of gravity = mass x 10m/s2

Eureka! explains the difference between weight and mass, and shows how only mass is the same on the moon and on the earth.

Building on the concept of inertia, Eureka! adds the factor of mass, tells how it's measured, and shows how it differs from size. Concept: Inertia increases with mass.

Aquest vídeo introdueix el concepte d'inèrcia, la pirmera llei de la física. A les coses els hi agrada continuar fent el que estaven fent.

Petit vídeo que il·lustra d'una manera molt gràfica la diferència entre calor i temperatura.

Petit video animat que explica de manera molt aclaridora en que consisteix l'energia potencial.

Aclaridor video de dibuixos animats que explica de manera senzilla i entretinguda en que consisteix l'energia cinètica.
