Can someone experienced with mousetrap cars help me check this worksheet? And I am very confused on #2, 5 and then 3 on "build considerations".

Mousetrap Car name of car: Mousey names of builders: Laylay Emily, Melina Energy The mousetrap stores _potential energy in the spring. This is converted into Kinetic energy in the form of the arm rotating forward. Mechanical Advantage 1. mechanical advantage of the arm = metal spring arm length 4 h c modified arm length 4.5 (m 18.5 con = 0.24 14.5 cm 2. The mechanical advantage of the arm is less than one. Explain what this means in terms of applied force outputted at the end of the arm and the distance the force is applied. The force is applied over a longer period of time = longer distance. since work does not change it means that a lower force is applied . 3. mechanical advantage from dowel to wheel = drive wheel dowel diameter wheel diameter 0. 3 cm = 0. 025 12 cm 4. The total mechanical advantage is found by multiplying the two individual mechanical advantages. Show the calculation to find MAtotal. MA total = 0. 025 x 0,24 = 0. 006 5. Explain how the result from #4 is useful for a mousetrap car designed to travel as far as possible. If the force out is less than the force in , that means the distance will be further if work stays the same Build Considerations 1. Where in your design are the major sources of friction? (axles ) Is the car moves , the wheels slide and there is friction between the cardboard body and the hot glue that attaches the wheels . We used to attach the string to a little hook on the axle but that led the string to get caught and not uncoil funy . 2. What are some improvements you would make to your design if you were to repeat this assignment Make the hot glue " heater " . lesser surface area for less friction . we could make the wheels straighter because it still veers a bit : 3. After the mousetrap arm reaches the end, the car keeps travelling forward. Explain why this is the case even though the mousetrap is the only source of energy to move the car. The wheels store energy . and when the string releases the axle is " flung " and travels further . CamScanner
