It represents motion under no acceleration (only due to ( u )).\n- ( \frac{1}{2}at^2 ): This accounts for the additional distance gained due to constant acceleration over time ( t ). The factor of ( \frac{1}{2} ) comes from integrating acceleration over time to obtain displacement.", "---", "### When to Use the Formula", "The formula applies strictly to uniformly accelerated motion, meaning the velocity changes at a constant rate.

Units Matter: Ensure all values are in compatible units (e.g., m/s for velocity and m/s² for acceleration).\n2. Sign Convention: Recognize direction: positive acceleration increases speed in the chosen direction; negative acceleration (deceleration) decreases it.\n3. Break Problems into Steps: Identify known variables first, then substitute into the formula, and compute carefully.\n4.
