To "propel" something means to make it move. This is a scientific-sounding word:

Water heated into steam propelled horseless carriages long before the development of the internal combustion engine.

The force of the explosion propelled their bodies forward and onto the ground.

When you want to tell what medium something is moving through (water, air, outer space, a crowd of people, etc.), use "propel ___ through":

They're propelled through the air by massive turbine jets at hundreds of miles per hour.
