AP Physics C Lab Report i. Purpose: To investigate the relationship in Newton’s Second Law ii. Materials: Pasco track and cart, endstop, pulley, string, washers, lab pro with motion detector, logger pro iii. Procedure: 1. Assemble the materials as shown in the diagram to the left.
The level required is 4 shuttles at level 5 (5.4). You will run 44 shuttles to reach this level. You are likely to pass if you can run 1.5 miles in 12 minutes or run on a treadmill for 8 mph for 12 minutes at zero gradient. (2) Dynamic Strength Test (Push-Pull) This test is carried out on a Concept 2 DYNO machine. After 3 warm up pushes, you will then have to push as hard as you can 5 times.
Find the mass of the 5 dry pennies, then record the data. 2. Add 5 more pennies to the first group for the mass of 10 pennies, record mass. 3. Repeat step two, then continue adding 5 dry pennies each step to balance until you have used all 30 pennies 4.

Hold the cart so that its rear axle is learned in 74, releasing the cart from notch A results in the fastes cart speed. Release the cart, and observe what happens. Measure the distance that the block moved down the track. Record the data as trial in your table. repeat steps 3-5 fourmatines and record data as trails 2-5.
Module 3: Natural Forces Affecting the Driver Vocabulary: Please define six (6) of the following terms in your own words. Please do not just copy and paste the definition. 1. Gravity - The force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.
So the resolution error value would not be included in the precision uncertainty calculation. The equation of t- value is shown in below: (7) The degree of freedom was obtained by Equation 8. v=N-1 (8) The total random error was calculated by root sum of squares (RSS) shown below up=±upi2 (9) The bias error was equal to the bias error of instruments. ub=ubi2 (10) The total uncertainty was the square root of total random error square plus total bias square. ux= ub2+up2 (11) The total uncertainty could be found by using Partial Derivative Method. The general equation is shown below uρ=(∂ρ∂mum)2+(∂ρ∂lul)2+(∂ρ∂huh)2+(∂ρ∂wuw)2+(∂ρ∂dud)2 (12) The partial derivative for each variable is shown below: ∂ρ∂m=1hlw-πd24w (13) ∂ρ∂l=-hmw(hlw-πd24w)2
The question to be answered by performing this lab is how can the coefficient of static and kinetic friction be determined for an object on a horizontal surface?

The motor torque Tm (Nm) can be approximately modelled as Tm = K I, where K is the DC motor torque constant and I is the motor current (A). The Mechanics The model we are dealing with is a simplified version that neglects the rotational inertia of the wheels and other components of the motor system. The torque on the wheel is directly proportional to the motor torque Tm therefore T = Tm = K I can be directly calculated. The forces we will be dealing with are; the forward propulsion force (F) generated by the rear wheels, the gravitational force (W = M g) and the drag force due to friction (Fd). Mathematical Relationships The relationship between acceleration, velocity and distance will help us to model the performance of the car.
