GPE = m × g × h
[ 1\ \textJ = 1\ \textN \cdot 1\ \textm ]
Efficiency is a measure of how much of the input energy is converted into useful work. It is calculated using the equation: GPE = m × g × h [
: The graph is a straight line passing through the origin, indicating that the force is directly proportional to the extension ( ), provided the elastic limit is not exceeded. Calculating Work Done : The area under the graph represents the work done ( ) to stretch the spring. For a linear graph, this is the area of a triangle: Example Calculation : If a spring stretches ) with a force of , the work done is: Data Analysis Steps In this activity, you are generally expected to: Plot the Graph : Ensure the -axis (Force) and -axis (Extension) are labeled with correct units.
Because this is a creative design question, there is no single "correct" answer. However, your design should be based on sound physics principles. The official answer guide provides a framework of key points your model should demonstrate. For a linear graph, this is the area
