In which we discuss the acceleration and its relation to velocity – when it is zero and when it is not, and how it relates to objects speeding up or slowing down.

In which we talk about the wavelength, the frequency and the velocity of waves.

In the latest episode, we talk about distance and displacement and the difference between them. We also calculate the average velocity and the average speed of a polar bear.

We discuss Tsunami and how they travel, the speed of waves and the energy they transport. We also talk about what Intensity is and how it depends on the distance from the wave source.

In which we visit the farmer’s market in search of deals on watermelons, learn how volume and surface scale, and watch out for non-linear units.

In which we introduce the Metric System of Units and talk about prefixes.
