WebFeb 18, 2024 · $\because$ Flywheel Energy Storage One way to store energy is in the rotational motion of a flywheel, and some have proposed using such technology to power automobiles. One unit is based on a $6.0-\mathrm{kg}$ flywheel in the shape of a hoop of radius 0.10 $\mathrm{m}$ that spins as fast as $60,000$ rpm. WebFigure 3. Experimental vehicles, such as this bus in Figure 10.16, have been constructed in which rotational kinetic energy is stored in a large flywheel. When the bus goes down a hill, its transmission converts its gravitational potential energy into KE rot. It can also convert translational kinetic energy, when the bus stops, into KE rot. The ...
