Electricity can be turned into propulsion through electric propulsion technology which uses electrical energy to accelerate charged particles such as ions to generate thrust which is most commonly used in spacecraft to maneuver and adjust their orbits.
The electricity is used to push a propellant out and create forward momentum for the spacecraft.
Another that electricity is turned into propulsion is through an electric motor.
The electricity spins the electric motor which in turns propels something such as a scooter, electric bicycle, car etc.
An example of propulsion force is a car engine that propels a car forward or a rocket engine that launches a spacecraft into space.
To create propulsion the burning of fuel creates hot gas which is then expelled through a nozzle to generate the thrust needed to propel the rocket forward.
Any exact which pushes an object or something to move including a car engine driving a vehicle or even a person that is walking by pushing off the ground are also examples of propulsion.
When you drive your car the engine burns fuel which turns makes the engine run and turn the engines crankshaft to engage with the transmission to propel the car forward down the road.
Essentially propulsion is simply the act of driving an object forward or pushing an object forward.
When you pedal a bicycle you're propelling the bicycle forward with your feet on the pedals.
A propulsion system also uses a source of power to create thrust.
This thrust then pushes against an object like a car, airplane, rocket etc to move it forward.
The amount of thrust that is created depends on the mass flow through the engine and also the exit velocity of the gas.
Walking, flying and airplane, launching a rocket and driving a car or other vehicle are all examples of propulsion.
There are several types of propulsion systems which include rocket propulsion systems, electric propulsion systems, gas turbine engines and internal combustion engines.
