Match the process with the fundamental interaction responsible for this process.
1)A falling object slows down from a great speed to its terminal velocity.
2)An apple is held off the ground by the surface of a table.
To match the processes with the fundamental interactions responsible for them, we need to understand the nature of these interactions.
1) A falling object slowing down from a great speed to its terminal velocity is related to the interaction known as gravity. Gravity is responsible for the attraction between objects with mass, causing them to move towards each other. In this case, the falling object experiences a force due to gravity, which initially accelerates it and then gradually slows it down until it reaches terminal velocity.
2) An apple being held off the ground by the surface of a table is related to the interaction known as electromagnetism. Electromagnetic forces arise from the interaction of charged particles. In this case, the electrons in the atoms of the table repel the electrons in the apple, creating a force that opposes the gravitational force pulling the apple downwards. This repulsion between the electrons at the atomic level allows the apple to be held in place above the table.
In summary:
1) A falling object slows down from a great speed to its terminal velocity - fundamental interaction: gravity.
2) An apple is held off the ground by the surface of a table - fundamental interaction: electromagnetism.
