Investigation B: Energy Loss Due to Air Resistance Purpose: to observe the loss of mechanical energy of a falling object due to air resistance Materials: a sheet of paper and a motion detector Procedure: 1) Place your motion detector face up on your table and start up LoggerPro. Grab 10 sheets of paper from the scrap paper bin by the printer. Take one of the sheets of paper and hold it 50 centimeters above the detector. Hit the collect button to begin recording data. When you start to hear the clicks from your motion detector, let the paper go. Stop recording data after the paper lands on the motion detector. 2) Use your data to determine the speed of the paper just before it landed on the detector. Record your measurement below. v= 0.75 m/s 3) Find the mass of your sheet of paper. To do this, place all 10 sheets on the triple beam balance and find their mass. Then divide by 10 to get the mass of a single sheet. Record your measurement below, in units of kg. m= 0.0047 kg 4) Calculate the initial mechanical energy (Ei) of your sheet of paper. Use the equation below and set the height to h = 0.50 meters, and the speed to v=0. E = mgh+1/2 mv² E= J 5) Calculate the final mechanical energy (Ef) of your sheet of paper by setting the height to h = O and the speed to the value you measured in step 2. F = moh+1/2 m2 E = J 5) Calculate the final mechanical energy (Ef) of your sheet of paper by setting the height to h = 0 and the speed to the value you measured in step 2. E = mgh+1/2 mv² E = J 6) How much energy was lost due to air resistance (Ei- Ef)? Where did the lost energy go (i.e., what forms of energy might it have been converted to)?
