Solve each formula for the indicated variable. Assume that the denominator is not 0 if variables appear in the denominator.
$s=\frac{1}{2} g t^{2}, \quad$ for $g \quad$ (distance traveled by a falling object)

Key Concepts

Domain Restrictions

When solving equations, it is important to consider the domain of the variables, particularly when a variable appears in a denominator or under a radical. Domain restrictions ensure that the operations performed (like division) are valid, meaning that values causing undefined expressions (such as division by zero) are excluded.

Inverse Operations

Inverse operations are the techniques used to reverse the effects of another operation, such as using multiplication to counteract division or using subtraction to cancel addition. This concept is fundamental in transforming and manipulating equations in order to solve for an unknown variable.

Algebraic Manipulation

This is the process of rearranging equations by applying arithmetic operations to both sides in order to simplify or alter the form of an equation. It involves combining like terms, distributing multiplications, and using addition, subtraction, multiplication, or division to shift parts of the equation, making it easier to solve for the desired variable.

Isolating a Variable

Isolating a variable involves rewriting an equation so that the variable of interest appears alone on one side. This typically requires applying inverse operations to both sides of the equation to systematically remove any coefficients, factors, or additional terms attached to the variable.
