1. Forces and Movements
Eureka! - Inertia

Eureka! - Inertia

Objects like to remain the way the are: static or moving. That laziness is called inertia. Learn about it.

Produced by TVOntario

Eureka! - Mass

Eureka! - Mass

Learn how the inertia of a body relates to its mass.

Eureka! - Forces and speed

Eureka! - Forces and speed

Learn how the force needed to move an object depends on the mass of the object and how much you want to increase its speed.

Produced by TVOntario

Eureka! - Acceleration (I)

Eureka! - Acceleration (I)

That was not quite true. In fact, the force depends on the mass of the object to move and how fast you want to increase its speed. Watch it.

Eureka! - Acceleration (II)

Eureka! - Acceleration (II)

Let a locomotive driver show to you that acceleration is how much the speed of an object changes every second.

Theory of gravity tested on the Moon

Theory of gravity tested on the Moon

Drop a hammer and a feather on the Moon, and which one will hit the surface first?

Eureka! - Buoyancy

Eureka! - Buoyancy

Learn that the buoyancy of an object is the result of a balance between two forces: the weight of the object and the weight of the displaced fluid.

Eureka! - Measuring temperature

Eureka! - Measuring temperature

You need something better than just "too cold" or "too hot", don't you? Learn how Anders Celsius came up with the solution…

Temperature

Temperature

Can an individual atom be hot or cold? Can it even have a temperature? Find out now!

Produced by Cassiopeia Project

Eureka! - Conduction

Eureka! - Conduction

Learn that heat can be transmitted by the vibration of an atom (or molecules) to its neighbours… which is what makes metals be so good heat conductors.

Produced by TVOntario

Eureka! - Convection

Eureka! - Convection

Learn that heat can also be conveyed by fluids thanks to the principle of buoyancy.

Eureka! - Radiation

Eureka! - Radiation

And lastly, heat can also travel in the form of waves.
