Propulsion

Propulsion

What is it?

Propulsion is when a body is moved in some direction because force is applied to it.

Give me an example!

Propulsion can come from many different sources.
Wind energy pressing against a sail moves boats through water. Thrust from a jet engine provides propulsion to aircraft. Mechanical energy generated by an internal combustion engine moves an automobile.
