Aerodynamic heating: Difference between revisions

Revision as of 13:32, 2 January 2008

Drag causes friction and that friction causes heating. It is a result of the mass resisting a change in velocity.

At very high altitudes and very high speeds the individual molecules in the atmosphere need to be pushed out of the way of an object reentering.
