Common mistake
Incorrect Unit Usage in Gradient Calculations
Students often forget to use consistent units when calculating the gradient of a velocity-time graph, leading to incorrect answers.
Always ensure that the units for both axes are consistent. For example, if the velocity is in m/s, the time should be in seconds, and ensure to express the gradient in appropriate units like m/s².
