Name : Date: Lab Investigation - 'Pterry' the Pterodactyl The Assignment You now are (hopefully) comfortable with the concept that L = Im for an object to exhibit uniform circular motion, the centripetal force needs to be 'supplied'. In this challenge, you and your group members are to calculate the necessary mass required to hang on the end of a long section of fishing line to keep Pterry flying with uniform motion when assigned a specific length 'L' value. mass The Procedure 1/ - Using your combined knowledge of centripetal force, derive an equation that will allow you to determine the magnitude of the required tension in the fishing line. 21 - Once an equation has been derived, determine what measurement(s) will need to be made. Measurements: Mpterry = 134 9 mcup = 5, 59 for storing the pennies 3/ - Calculate the number of pennies you will need to place in the holder in order to produce the required tension in the fishing line. MASSpenny = 2 . 2 9 The Assessment Derivation - TA Performance - APP Ten Marks will be allotted for a complete, Five marks will be allowed for performance. formal, elegant solution showing your Once released, the motion of your mass will be derivation and measured/calculated evaluated with respect to the following criteria: quantities. Measured Quantities 0 . 1 . 2 Mass: - does not move ( 21 cm 21/2 Derived Equation 3 . 4 . 5 . 6 - proper 'physics' used - inputted values/expressions sig figs, units, etc - explaining statements - elegance
