EVERYDAY SCIENCE

Detailed explanation-1: -The rider’s muscular energy is converted to heat energy and the bicycle’s kinetic energy while riding a bicycle. The rider’s body is heated by heat energy. The bicycle is propelled in a circular motion by kinetic energy.

Detailed explanation-2: -You pedaling the bike is transforming chemical energy, supplied by the breakdown of the food you eat, into mechanical energy to turn the pedals. The chemical energy is potential and the mechanical energy is kinetic.

Detailed explanation-3: -Instead of using gasoline or diesel fuel like motorized vehicles, bicycles turn our energy, created by our bodies, into kinetic energy . A bicycle can convert up to 90% of a person’s energy and movement into kinetic energy, making it the most efficient transportation mode to date.

Detailed explanation-4: -A bike rolling down a hill is an example of kinetic energy, where potential energy is constantly converting in the kinetic energy of the bike as given by 21mv2.

Detailed explanation-5: -The force used by pedaling enables the gears of a bike to spin the back wheel. As the back wheel rotates, the tire uses friction to grip the area and move the bike in the desired direction.
