Front

How do you solve for a variable in a linear equation?

Back

Isolate the variable on one side of the equation using algebraic operations such as addition, subtraction, multiplication, or division.

Front

What is the relationship between acceleration, time, and final velocity?

Back

Final velocity increases with time if acceleration is constant; the longer the time, the greater the final velocity.
