Secret Lab 1: Forces
Find out about forces with Professor Knowitall, Dr Spark and Dr Bright!
Factual series (2011). Series 1. Explaining all the mysteries of the world of science in BSL! In this episode, Professor Knowitall and his sidekicks, Dr Spark and Dr Bright, explain how forces govern our world. But how are forces measured? What part do magnitude, direction and resistance play? Dr Spark visits an ice rink to show how the size of each surface area affects how fast she can skate, and in turn, how friction works! Professor Knowitall then shows why boats travel faster with a V-shaped bow. Produced by Drip Media and Remark! Production for BSLBT.
