the engine inside causes the propeler to spin
Backwards spin
Your question is sort of backwards, perhaps you meant what causes engine failure? Engine failure causes...the engine to fail. If someone told me their engine failed I would take it to mean that it stopped running, or wouldn't start.
The wheels only appear to spin backwards.
With a 2 stroke or 2 cycle engine if the ignition timing is set too close to top dead center it can start to run backwards.
You may have the thermostat in backwards. The spring side of the thermostat faces into the engine.
Because any time anybody's foot is touching it, the foot is pushing it backwards.
A McTwist is an off axis spin while doing a 360. Riding backwards in snowboarding terms would be riding "fakie".
Yes, its a fakie 360 spin. Fakie meaning riding backwards in your a regular position, then 360 spin.
In a way. It is the difference between temperatures at the inlet and outlet of the steam turbine (generically, a 'heat engine') which results in the turbine spinning -this, in turn, causes the generator to spin.
Spin causes electrons to have an intrinsic magnetic moment, leading to the phenomenon of electron spin. This property allows electrons to interact with magnetic fields and is crucial for understanding the behavior of atoms and molecules in chemistry and physics.
Helicopter blades spin due to the engine providing power to the rotor assembly, which causes the blades to create lift and generate thrust. The rotation of the blades also allows the helicopter to maneuver and change direction in flight.
