Question

dominos standing in a row will all fall if the first one is tipped toward the others. how does the law of conservation of energy describe this?

Answer 1

When placing each domino upright, potential energy is conserved in that domino. When kinetic energy is initially added into the first domino, this energy converts the next domino's potential energy to kinetic energy, which is transferred to the next domino afterwards. Hope this helps ;3
