Welcome to the board. Pick a topic or ask me anything, and we will work through it one step at a time. Here is what happens when I write a formula — the energy stored in something that is moving:

$$\textcolor{#22d3ee}{E} = \frac{1}{2} \textcolor{#fbbf24}{m} \textcolor{#d946ef}{v}^{2}$$

Read it symbol by symbol: $\textcolor{#22d3ee}{E}$ is the energy, $\textcolor{#fbbf24}{m}$ is the mass, and $\textcolor{#d946ef}{v}$ is the speed. Notice that $\textcolor{#d946ef}{v}$ is squared, so doubling the speed does not double the energy — it quadruples it. Each symbol keeps its colour everywhere it appears, so you can follow $\textcolor{#fbbf24}{m}$ and $\textcolor{#d946ef}{v}$ through everything that comes next. What shall we start with?
