Answer
Initial velocity
Explanation
'u' stands for the initial velocity in the equation v^2 - u^2 = 2as, which is crucial for calculating changes in motion under uniform acceleration.
Common mistake
Misunderstanding the Uniform Acceleration Equation
Students often confuse the variables in the equation v² - u² = 2as, leading to incorrect calculations of final velocity, initial velocity, acceleration, or distance.
To fix this, students should carefully identify each variable: v is final velocity, u is initial velocity, a is acceleration, and s is distance. Practicing with example problems can help reinforce the correct application of the equation.
