![]() These can be used to prompt students' thinking. One of the chief values of real-time data-logging, exemplified here, is the interaction between the collection and simultaneous display of results.A straight line is the usual result, showing that the velocity squared is proportional to the height fallen. Use the program to calculate a new column of data representing the square of the velocity.This is usually of the form 'velocity is proportional to the square root of height'. ![]() (Y axis: velocity X axis: height fallen.) Use a curve matching tool to identify the algebraic form of the relationship.
