Propulsion has everything to do with swimming!! if it wasn't for propulsion you wouldn't move through the water. three elements of propulsion in swimming are:
hope this helps
A simple way to put it would be; - Decrease drag - Improve propulsion

Umm...the question is a little vague (is it for a project, are there more details?), so I'll offer as much as I find relevant. You can split it into arm propulsion or leg propulsion. You can split it into the four strokes: butterfly, backstroke, breaststroke, freestyle. You can split it into surface propulsion and underwater propulsion. Be more specific and I can help you more.
So you do not drown. And whenever you swim remember God is there and will help you if you trust in him.
Propulsion
MIT researcher James Czarnowski made observations of penguins swimming. He observed how quickly and easily the penguins moved through the water. By 1997, he had designed a "flapping" propulsion system that was more efficient than propellers.
Its main function is to propel itself when swimming. This is different from sharks since they use their caudal fins as its main propulsion force.
Some synonyms for propulsion are drive, energy, momentum, power, speed, or thrust. Propulsion is a noun, there is no antonym except 'no propulsion'.
The telson is the terminal segment of the abdomen in crustaceans, such as lobsters or shrimp. It helps with propulsion and acts as a rudder during swimming movements. Additionally, the telson often plays a role in defense by aiding in the delivery of a sharp sting or pinch.
The aircraft's propulsion comes from its engines.
There is one gastrocnemius muscle in each hind leg, between the knee and the foot. Its contraction provides propulsion, whether the frog is swimming or jumping.
Squids use their tentacles for propulsion.
