This lab activity focuses on determining acceleration using the equation $v^2 = v_0^2 + 2ax$, where $v$ is the final velocity, $v_0$ is the initial velocity, $a$ is the acceleration, and $x$ is the displacement. By measuring the initial and final velocities of an object over a known distance, we can rearrange the formula to solve for the object's acceleration. This method is useful in various physics experiments and real-world applications, such as analyzing the motion of vehicles or projectiles.
The key to this activity is accurate measurement and careful application of the formula. Understanding how each variable contributes to the overall equation is essential for successful calculation of acceleration. Make sure to pay attention to units!
