# How does the riders ability to stop the bike change as the bike moves down a steep hill?

## What happens to your potential energy as you ride your bike down a hill?

As the rider moves up the hill, her kinetic energy increases, and her potential energy decreases. … When the rider goes down the hill, her potential energy increases, and her kinetic energy decreases.

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

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.

## Is biking downhill mechanical energy?

Explanation: The bike is has kinetic or motion energy when it is moving downhill. When brakes apply, the energy is transformed into thermal energy on your brake (heat) and sound energy since you can hear it.

## Do the rider and bicycle have energy while coasting down the hill if so explain?

Yes, the rider and bicycle have energy when coasting down the hill because moving objects have energy.

## How does the potential energy of a bicycle transformed into kinetic energy?

Answer: The muscular energy of the cyclist is converted into kinetic energy (rotational) of the pedals of the bicycle which is transferred to its wheels. The kinetic energy of the rotation of the wheels is converted into the kinetic energy of the bicycle and the cyclist.

## What is the energy transformation in riding a bike?

Therefore,when riding a bicycle the rider’s physical energy is converted to the bicycle’s heat energy and kinetic energy. During transformation, the total energy remains conserved. Hence,the various energy transformations that occur when you are riding a bicycle are muscular energy to kinetic and heat energy.

## What energy is used in cycling?

The aerobic energy system is the superstar of cycling and provides most of the body’s ATP. The aerobic system is the slowest in creating ATP and fuels efforts longer than a couple of minutes.

## Is riding a bicycle kinetic energy?

Bicycling is a rich source of kinetic energy. … This kind of device would operate on a simple principle: the rotational force of peddling the bike causing the wheels to spin, this spins a rotor that spins a generator, ultimately producing electricity which is then stored in a battery.

## How can cycling save energy?

Here are some of the skills and techniques you can use to be more economical with how and where you expend energy on the bike.

1. Think Big, Act Small. …
2. Idiots ride in the wind. …
3. Momentum is King. …
4. Don’t be a One-Hour Hero. …
5. Stop digging. …
6. Eat and drink with purpose. …
7. Have each other’s backs.

## What happens to a bicycle mechanical energy when you apply the brakes and stop?

What happens to this mechanical energy when you apply the brakes? When you apply the brakes, the bicycle’s mechanical energy is transformed into thermal energy as the brake pads rub against the bicycle’s wheels. … The additional thermal energy warms the brakes, the wheels, and the air around the bicycle.
