How Do Dominoes Fall?

What caused the domino at the end of the row to move?

The student placed one hundred dominoes upright in a row. He knocked over the first domino and the rest all fell over; one after another.

Answer:

Newton's first law; an object will stay at rest until a force is added onto it. Since the student knocked over the first domino that force the student added continues on until the row ends.

When a student places one hundred dominoes upright in a row and knocks over the first domino, it sets off a chain reaction where each domino falls onto the next one, causing a continuous movement until the last domino falls. This phenomenon can be explained by Newton's first law of motion, which states that an object will stay at rest until a force is applied to it. In this case, the force applied by knocking over the first domino initiates the motion of all the other dominoes in the row.

Explanation:

The reason why the domino at the end of the row moves is because of the transfer of energy from one domino to the next. As each domino falls, it releases potential energy that is converted into kinetic energy, causing the next domino to fall. This process continues until all the dominos have fallen.

So, the next time you see a row of dominoes falling one after the other, remember that it's the result of Newton's first law in action, as well as the transfer of energy from domino to domino!
