Common Mistake in Rearranging Work Done Equation
Students often confuse the variables when rearranging the equation W = Fs, leading to incorrect calculations of work done, force, or distance.
To fix this, students should clearly identify which variable they need to isolate and carefully rearrange the equation step by step, ensuring they understand the relationship between work, force, and distance.
