INTRODUCTION: Newton's second law of motion states that the acceleration (a) of an object is directly proportional to the net force (EF) acting on it and inversely proportional to its mass (m) ΣΕ (1) m Since the acceleration depends on 2 quantities, mass and force, we will make two separate sets of measurements of the acceleration of a glider: First we will apply a fixed force, the hanging object, to the glider, and find the acceleration each time we change the glider's mass. Then we will keep the total mass fixed and measure the acceleration each time 2. Photogate timer and accessory photogate. 4. Triple-beam balance. we change the net force. APPARATUS: 1. Air track system with one glider. 3. Various small masses and hangers. FLAG glider AL 1.H HE
ANALYSIS: FOR PART A AND PART B: 1. From the width of the flag (AL) and the times At, and At, that it took the flag to pass through the first and second photogate, respectively, calculate V₁ and V₂ using AL ΔΙ P₁ = and V₂ = (3) At₁ ΔΙ 2. Record these values in the table 1 for part A and in Table 2 for part B. 3. Use the definition of acceleration V₂-V₁ ā= (4) At, To determine the average acceleration of the flag as it passed between the two photogates. (Note: we are assuming here that v₂ and v₁ are not much different from V₂ and v₁). I 4. Plot graphs of the experimental and theoretical values of the acceleration on the vertical axis and / (M+ m₂) on the horizontal axis. Table 1 has the necessary information. 5. Draw a second set of graphs of the experimental and theoretical values of the acceleration as a function of the applied force m.g. Table 2 has the necessary information. 6. Examine your graphs carefully. Use your graphs to determine the relationship between the average acceleration, net force and the total mass. 7. Calculate the percentage difference between the theoretical and experimental values of the acceleration. a= m.g M+m. a exp At.
Measurements And Units Mass of the glider-85.4 grams. Length of the flag on the glider = 2.5 cm. All the masses are in grams, time in seconds, velocity in cm/s, acceleration in cm/s², and force is in Dynes. (1 Dyne=10°N) TABLE 1.
