## What type of energy is pedaling a bike?

Bicycles turn energy created by our bodies into kinetic energy. Kinetic energy is “a property of a moving object or particle and depends not only on its motion but also on its mass” (Encyclopedia Britannica).

## What type of energy is used when riding a bike uphill?

The energy is in motion, so it’s kinetic energy, and it’s derived from the food we digest – the primary fuel for cells is glucose. At the top of the hill, in the absence of motion, the kinetic energy converts to potential energy.

## Is riding a bike an example of mechanical energy?

When you ride a bicycle, several things happen that require energy and it’s transformation. 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.

## How is energy transferred in a battery operated toothbrush?

How is energy transferred in a battery operated toothbrush? An induction charger is two halves of a transformer, with a coil in each section. The mains electricity in the coil of the base induces a trickle of current in a smaller coil in the toothbrush, to charge the battery.

## In which order does energy change from one type to another when you ride a bike and then stop?

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.

## How does cycling uphill affect the maximum speed?

Since the power required to overcome air resistance is proportional to the bicycle speed cubed (if there is no wind, and s = v), an exponential increase in power is needed as the cyclist attempts to increase speed. Going uphill adds gravity to the forces that must be overcome.

## What is the best example of a device that converts electrical energy ⇒ thermal energy?

Examples of Electrical Energy to Thermal Energy Conversions: 1. A toaster draws electric current (electrical energy) from a wall outlet and converts these moving electric charges into heat (thermal energy) in the filaments that turn red hot to cook your toast.
