1. Since the graph is linear and contains (0,0) Force exerted by a spring vs. Elongation Review of an Ideal Spring

2. Since the force exerted by the spring and the elongation are always in opposite directions Hooke’s Law Holds for ideal springs Spring Constant ( k ) – the slope of a graph of the force exerted by a spring vs. its elongation. – a measure of the elasticity (strength) of a spring Review of an Ideal Spring

3. Period of a Mass on a Spring Pre-Lab What variables might affect the period of a mass on a spring? Period Mass Amplitude Spring Constant Period

4. Period of a Mass on a Spring Pre-Lab What variables might affect the period of a mass on a spring? Period Mass I D Purpose: To create graphical and mathematical representations of the relationship between the period, mass and spring constant of a mass on the end of a spring. Spring Constant I Period
