NASA G2 flywheel. Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy.When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the ...
Most cycling power meters use strain gauges to measure torque applied, and when combined with angular velocity, calculate power. [1] The technology was adapted to cycling in the late 1980s and was tested in professional bicycle racing i.e.: the prototype Power Pacer (Team Strawberry) and by Greg LeMond with the SRM device. This type of power ...
Vacuum trajectory of a projectile for different launch angles. Launch speed is the same for all angles, 50 m/s, and "g" is 10 m/s 2. To hit a target at range x and altitude y when fired from (0,0) and with initial speed v, the required angle(s) of launch θ are:
Reducing the weight of the bike + rider by 1 kg would increase speed by 0.01 m/s at 9 m/s on the flat (5 seconds in a 32 km/h (20 mph), 40-kilometre (25 mile) time trial). The same reduction on a 7% grade would be worth 0.04 m/s (90 kg bike + rider) to 0.07 m/s (65 kg bike + rider).
English: Trajectories of projectiles launched at different elevation angles and a speed of 10 m/s. A vacuum and a uniform downward gravity field of 10 m/s² is assumed. t = time from launch, T = time of flight, R = range and H = highest point of trajectory (indicated by arrows). The points are at 0.05 s intervals.
