A student placed one hundred dominoes upright in a row. He knocked over the first domino and the rest all fell over; one after another. What made the domino at the end of the row move?
a
Kinetic Energy
b
Thermal Energy
c
Potential Energy
d
Chemical Energy
a. Kinetic Energy
The domino at the end of the row moved due to the transfer of kinetic energy from the falling dominoes that came before it. As each domino fell, it transferred its energy to the next domino in line, causing a chain reaction until the last domino fell.
