Newton's Laws Lab Name: Data Collection—Table 1: Trial Force used (N) Time (s) Distance (m) (fixed) Acceleration (m/s 2 ) Mass (kg) 1 50 9.6 5.0 0.108 463 2 100 7.5 5.0 0.177 564 3 150 5.6 5.0 0.318 471 Analysis 1. Using the equation, the value of 5.0 m for the distance, and the time that you recorded for a wagon to reach the stop block, calculate the acceleration for each trial. Show your work. Fill in Table 1 with your answers. Trail 1: 2*5.0m/(9.6)^2=0.108 m/s^2 Trail 2: 2*5.0m/(7.5)^2=0.177 m/s^2 Trail 3: 2*5.0m/(5.6)^2=0.318 m/s^2 1. Using Newton's second law of motion, calculate the mass of the cart for each trial. Show your work. Fill in Table 1 with your answers. Trail 1: 50N/0.108 m/s^2=463 kg Trail 2:

100N/0.177 m/s^2=564 kg Trail 3: 150N/0.318 m/s^2=471 kg Questions Answer questions in complete sentences. 1. Compare the accelerations for the three trials. Explain how Newton's second law was demonstrated in the simulation. The data from the simulation aligns with Newton's second law, demonstrating the direct relationship between force and acceleration and the inverse relationship between mass and acceleration. 1. Describe how Newton's first and third laws would apply to this situation if this simulation was done in the real world. Newton's first law describes the inertia of the wagon, and Newton's third law highlights the equal and opposite forces between the wagon and the objects interacting with it. In a real-world scenario, factors like friction and air resistance would contribute to the complexities of the motion 1. Compare the masses that you calculated for the three trials. If the actual mass of the cart did not change (same cart for all trials), what measurement do you believe contributed the largest amount of error to that calculation? Explain your answer. If the actual mass of the cart did not change, any variation in the calculated masses would likely be due to errors in the measurements or calculations like time and assuming constant acceleration. The calculated outcomes are estimates that depend on assumptions made during the calculations. With perfect measurements and no external factors affecting the motion, the calculated outcomes should match the measured outcomes closely.

However, there may be differences between calculated and measured outcomes. The measured values could be influenced by factors such as experimental error, and variations in the environment. If the fall distance was 25 meters, the impact of reaction time would become more significant. Reaction time is the delay between the start of an event and the observer's response to it. In a longer fall, any delay in starting or stopping the timer would have a more substantial effect on the calculated acceleration. The longer the fall distance, the more sensitive the measurements become to reaction time. The reaction time itself does not necessarily increase with the length of the fall. Reaction time is a constant delay between the occurrence of an event and the observer's response to it. Reaction time can be subjective as well. If you have faster reactions and good timing, the smaller the percentage of the total fall time due to the finger movement there will be. The timing device used also plays a part in the accuracy of the timing. If the same observer is timing both the 2m and 25m falls, the percentage of the total fall time due to the finger movement should be pretty similar.
