3m 54s
In the second part of the unit for Forces, Density and Pressure, we are talking about frictional and viscous forces. Frictional and viscous forces act to oppose motion. They’re the reason why Newton’s first law is so unbelievable to most people. We discuss this and how pressure is related to force.
