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
Chemical Energy
b
Kinetic Energy
c
Potential Energy
d
Thermal Energy
b. Kinetic Energy
wrong its thermal
kinetic has something to do with water waves or something IDK but its thermal not kinetic
It is the motion of the one that hit it. Kinetic energy
The correct answer is b) Kinetic Energy.
When the first domino is knocked over, it gains kinetic energy. Kinetic energy is the energy associated with motion. As the first domino falls, it transfers its kinetic energy to the next domino, causing it to move and gain kinetic energy. This process continues down the line of dominoes, with each domino transferring its kinetic energy to the next one, resulting in a chain reaction causing all the dominoes to fall.
To find the answer to this question, you must have a basic understanding of energy types. You can differentiate the energy types by their definitions and characteristics. Kinetic energy refers to the energy of motion, and in this scenario, it is the energy that causes the dominoes to fall one after another.
You can also rule out the other options by understanding their definitions:
a) Chemical Energy: This refers to the energy stored in chemicals, such as fuel or batteries. It does not apply to the situation described.
c) Potential Energy: This refers to the energy stored in an object due to its position or state. While the dominoes may have some potential energy while standing upright, potential energy alone wouldn't explain why the last domino moves. Potential energy is transformed into kinetic energy when the first domino is knocked over, but it is not the answer to what makes the last domino move.
d) Thermal Energy: This refers to the energy associated with the internal motion of particles and is related to temperature. It does not play a significant role in causing the dominoes to fall in this scenario.
By understanding the definitions and characteristics of different types of energy, you can determine that the correct answer is b) Kinetic Energy.
