Speed

The video tutorial explains the concept of speed, which is how fast or slow something moves. It uses examples like a slow tortoise and a fast motorbike to illustrate different speeds. The tutorial also discusses how objects require a force to start moving, using a bobsleigh race as an example where the team pushes the sled to initiate motion. The bobsleigh then slides downhill on slippery ice, increasing its speed. The video concludes with a recap of the speed concept.
