What is thermal expansion for kids?
Thermal expansion is when something gets bigger (expands) as it gets hotter and smaller (contracts) as it gets colder. This happens because the particles inside the object move faster and spread out when heated, causing the object to expand. This phenomenon is why bridges have gaps and train tracks have small spaces between the rails.
How does a train get traction to move along the tracks?
A train gets traction to move along the tracks through the friction between the steel wheels of the train and the steel rails of the track. This friction allows the train to grip the track and propel itself forward. Additionally, the weight of the train pressing down on the wheels helps increase traction and stability.
