Gravity- the force that
attracts a body to the center of the earth. Friction- the resistance that one surface or object gets when moving over another. |
|
Aerodynamic- the study of the properties of moving air. And the interactions of solids going through the moving air.

Force- strength or energy as an attribute of action or movement.
Dynamics- the part of mechanics
concerned with the motion of bodies under the action of forces. |

Escape velocity- the lowest velocity that a body must have in order to escape
the gravitational attraction of a planet or another object.
the gravitational attraction of a planet or another object.
Drag- the resistance caused by
a gas to the movement of a solid body moving through it. |

stirling engine- a machine used to provide power or refrigeration, operating on a closed cycle in which a working fluid is cyclically compressed and expanded at different temperatures.

Multiple expansion engines - An engine in which the expansion of the steam or other working fluid is divided into two or more stages, which are performed successively in cylinders of increasing size

uniflow engines- A steam engine in which steam enters the cylinder through valves at one end and escapes through openings uncovered by the piston as it completes its stroke.

turbine engines - An internal-combustion engine consisting essentially of an air compressor, combustion chamber, and turbine wheel that is turned by the expanding products of combustion
|
rotary steam engines - The rotary engine was an early type of internal-combustion engine, usually designed with an odd number of cylinders per row in a radial configuration, in which the crankshaft remained stationary, with the entire crankcase and its attached cylinders rotating around it as a unit in operation.

The engine block is the main structural component of an engine. It supports and helps maintain alignment of internal and external components. The engine block consists of a cylinder block and a crankcase. An engine block can be produced as a one-piece or two-piece unit.

a disk or cylindrical part tightly fitting and moving within a cylinder, either to compress or move a fluid collected in the cylinder, as air or water, or to transform energy imparted by a fluid entering or expanding inside the cylinder, as compressed air, explosive gases, or steam, into a rectilinear motion usually transformed into rotary motion by means of a connecting rod.

A cylinder is the central working part of a reciprocating engine or pump, the space in which a piston travels.Multiple cylinders are commonly arranged side by side in a bank, or engine block, which is typically cast from aluminum or cast iron before receiving precision machine work.

crankshaft is a mechanical part able to perform a conversion between reciprocating motion and rotational motion. In a reciprocating engine, it translates reciprocating motion of the piston into rotational motion

Recoil start (also called manual start, pull start, or zip start) refers to a method of starting an internal combustion engine, usually on small machines, such as lawn mowers, chainsaws, ultralight aircraft and portable engine-generators.
electronic ignition system - is a electronic motor that turns the flywheel witch turns the crankshaft, witch turns over the engine

companion - is when you have a pull start or you have electric start .
