## Why is the principle of mathematical induction likened to the domino effect?

The domino effect is really a great analog of the above process. **The inductive step ensures that “dominoes are placed closed to one another, such as if one falls, then the next one will fall as well”**. The base case ensures that “the first domino is indeed pushed”. Visualizing mathematical induction.

## Can a domino knock down one that’s just slightly bigger than itself?

Physics research has shown that **a domino can knock over another one that is 1.5 times taller**. OK, this is what makes physics so cool.

## How is mathematical induction used in real life?

First standard example is **falling dominoes**. In a line of closely arranged dominoes, if the first domino falls, then all the dominoes will fall because if any one domino falls, it means that the next domino will fall, too.

## Is essentially used to prove that a statement P N holds for every natural number?

**Mathematical induction** is a mathematical proof technique. It is essentially used to prove that a statement P(n) holds for every natural number n = 0, 1, 2, 3, … ; that is, the overall statement is a sequence of infinitely many cases P(0), P(1), P(2), P(3), … .

## How do dominoes fall?

“When you pick up a domino and stand it upright, lifting against the pull of gravity, you store some potential energy in it,” he says. As a domino falls, **energy is converted from one form to another**. This change creates a chain reaction, causing domino after domino to topple.

## Why do dominoes fall faster closer together?

This is because **the more dominoes there are, the faster the speed is because of the weight adding up as each domino falls**. And, since more dominoes are needed for lining up a distance of 3.0m, the speed of 3.0m is faster than the speed of 1.5m for any distance between the dominoes shorter than 2.0cm.

## What happens to this energy when the first domino is pushed?

Each upright domino is also full of potential energy. When the first domino falls, the force of gravity turns that **potential energy into enough kinetic energy to topple a domino larger than itself**.

## How is the energy from the first domino able to topple the last domino?

How is the energy from the first domino able to topple to last domino? **the potential energy of the 1st domino is transformed into kinetic energy which is transferred to the 2nd domino, knocking it over.**

## How do you know that a falling domino that causes another domino to move has energy?

A line of falling dominoes is a good example of energy moving from one place to another. **A force (your finger) topples the first domino.** **The force of the falling domino topples the next and the next on down the line**. Besides converting all potential energy to kinetic energy, a transfer of energy has happened.

## What are the factors that affect the speed of falling dominoes?

All of the variables that affect the speed of a domino chain reaction — **the amount of time between impacts, how much force each tile applies to the next, and the velocity with which a tile hits the next in the line** — are affected by the distance between the tiles.

## How does distance affect speed?

**The faster an object is moving, the longer the distance it takes to stop**. If a vehicle’s speed doubles, it needs about 4X’s the distance to stop. If a vehicle’s speed triples, it needs up to 9X’s the distance to stop. Weight works in the same way that speed does in relation to stopping distances.

## What is the difference between speed and velocity?

**Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement**. Put another way, speed is a scalar value, while velocity is a vector.
