What forms of energy are involved in a bicycle coasting along level road?

1. Kinetic Energy: The bicycle has kinetic energy due to its motion. This energy is associated with the movement of the bicycle and its components, including the wheels, frame, and rider.

2. Potential Energy: As the bicycle moves along the level road, it has a certain amount of potential energy due to its height above the ground. This energy is stored within the system and is related to the bicycle's position relative to the Earth's gravitational field.

3. Friction: When the bicycle's wheels roll along the road, friction between the tires and the road surface opposes the motion. This friction converts some of the kinetic energy of the bicycle into heat energy, causing the tires and the road to warm up.

4. Air Resistance: As the bicycle moves forward, it encounters air resistance, which is a force that opposes the motion. Air resistance is caused by the interaction between the bicycle and the surrounding air particles. It also converts some of the kinetic energy of the bicycle into heat energy, dissipating it into the atmosphere.

5. Internal Energy: As the bicycle's components, such as the bearings and the chain, experience friction and resistance, internal energy is generated within the system. This energy manifests as heat, causing the components to warm up.

It's important to note that during coasting, the cyclist is not applying any additional energy to the system. Instead, the bicycle's kinetic energy is gradually lost due to friction and air resistance, eventually causing it to slow down and eventually stop.
