The speed ratio of a bicycle is the (gear ratio* radius of the wheel)/ Length of the pedal arm.
more than 1
ratio
18 miles on the bicycle, 60 miles on the motorboat.
The index of refraction.
It is the average speed.
The ratio of (distance) / (time), called "speed".The ratio of (speed) / (time), called "acceleration".The ratio of (force) / (area), called "pressure".The ratio of (force) / (acceleration), called "mass".The ratio of (mass) / (volume), called "density".The ratio of (distance) / (volume), sometimes called "fuel economy".The ratio of ( 1 ) / (time), called "frequency".The ratio of (energy) / (time), called "power".
the faster the speed of the bicycle,the brighter the lamp
Braking reduces speed.
Distance input --------------- = Speed Ratio Distance output The distance input divided by the distance output equals the Speed Ratio.
The output from the dynamo varies with the speed of the bicycle. And as a geared bicycle is likely(but don't have to) travel a bit faster than the single speed, it may produce a bit more electricity.

The top speed for a bicycle depends on the rider (strength, stamina, coordination, muscle speed), the gearing of the bicycle, and the terrain it is being ridden over. The current record speed is 268.831 km/h - which was set on a specially designed bicycle ridden behind a dragster (to eliminate most of the air drag) on October 3, 1995 on the Bonneville Salt Flats in Utah, USA.
Walking speed Bicycle speed Automobile speed Train speed Airplane speed Rocket speed
When he's gaining speed
swirl ratio = air rotational speed / crank shaft speed of an ic engine
The invention of the multi-speed bicycle increased the usefulness of the vehicle. It made it easier to pedal up hills giving it much more range.
Speed can be exoressed as a ratio
