Bicycle

Next time you ride a bicycle, be sure to thank mass, gears, and wheels. SERIOUSLY you need this equipment. If you try to go SLOWLY, then you will just fall, since no acceleration is found in the bicycle. Potential energy is changed into kinetic energy when you run down a hill, and kinetic energy is transformed into potential energy when you climb a hill. Gears will help you. On a kid’s bike, they have 2 gears, so it doesn’t take SOOOOOO much to climb hills, but you’ll have to RUN, so be sure to run enough calories. When gears rotate, they give the energy to the wheels.
