Illustrates the mathematical relationship between the force exerted by a spring and the associated elongation of the spring. Students will investigate this result of elasticity by hanging successively greater weights on the spring and recording how far the spring stretches.
|Springs, 12"||JE-105A-D58||1 per table|
|Weight Hangers, 100g||JE-105A-D42, D43, D45||1 per table|
|Timer, - MyChron, Battery||JE-105A-D62||1 per table|
|Meter Stick - 2.00m||JE-105A-(105 Door-L)||1 per table|
|Clamp, Pendulum||JE-105A-D65||1 per table|
|Masses, Slotted 100g||In Back of JE-105, 107 & 109||2 per table|
|Masses, Slotted 500g||In Back of JE-105, 107 & 109||2 per table|
For each table, there should be two 100g masses, two 500g masses, and a 100g weight hanger. Make sure that the screws on the pendulum clamps go THROUGH one of the holes on the ends of the springs. Do not just place the spring over the knob of the screw. Screw the spring on so it cannot become dislodged with motion. The zero mark on the 2 meter sticks should be on the floor.
Make sure that the room has plenty of paper. Along with the initial apparatus set-up, supply a sufficient number of the appropriate paper procedure handouts for all of the lab sections that will use the set-up over the course of the week. Print the PDF, duplicate to double-sided pages, staple, and leave pile on instructor's table prior to first use of set-up.
