Physics Labs with Computers, Vol. 1Student WorkbookP15: Simple Harmonic Oscillation 012-07000A3. Calculate the theoretical period for Run #2 using the values of the spring constants and themass of the cart and picket fence and mass bar.4. What is the percent difference between the measured and theoretical values for the period?5. Does the period of oscillation increase or decrease as the mass is increased?6. Is the spring constant value, k, the same for a spring when the spring is vertical as when thespring is horizontal? How can you test this?Optional• Change the initial displacement of the cart from equilibrium (for example, try 15 cm) andrepeat the data collection and analysis.Optional Question1. How does the period of oscillation change?Amplitude = cm Mass (kg) Period (s) Theoretical (s) % differenceCart aloneCart plus massAmplitude = cm Mass (kg) Period (s) Theoretical (s) % differenceCart aloneCart plus massp. 104 ©1999 PASCO scientific P15

When the energy is inside an object, it issometimes called internal energy or thermal energy. The thermal energy in an object is thetotal kinetic energy of all the particles that make up the object.Temperature is a measure of the average kinetic energy of all the particles in theobject. The number for the temperature of an object doesn’t tell you much about theactual kinetic energy of a particle inside the object. The number comes from atemperature scale such as the kind found on a common thermometer.A thermometer measures temperature by means of the expansion and contraction of aliquid, usually mercury or colored alcohol. The reason that this works is that the liquid ina thermometer expands or contracts in a predictable, repeatable way when it gains orloses thermal energy. For example, the mercury in a thermometer always expands to thesame level when the end of the thermometer is in boiling water. It always shrinks to thesame level when the end of the thermometer is in ice-cold water. The number on thetemperature scale is a way to make comparisons. If we say that a certain liquid has atemperature of 0˚ C, it means that the mercury in a thermometer put into this liquidwould shrink to the same level as it did when the thermometer was put into ice-coldwater.The amount of thermal energy in an object is related to temperature, but temperature by itselfcan’t tell you have much thermal energy is in an object. For example, a bed of glowing coals in afireplace might have a temperature of 600 ˚C while a single spark from the fire might have atemperature of 2000˚ C. The single “hot” spark gives off very little heat while the bed ofrelatively “cool” coals gives off a large amount of heat. The difference between the bed of coalsand the single spark has to do with both the temperature and the quantity of matter.Identical thermometers in two pots of water on a hot stovewill show different temperatures even if the pots have beenon the stove for the same time if the amount of water in onepot is different than the amount in the other.P16 ©1999 PASCO scientific p. 105
