The document describes three experiments conducted to measure the acceleration due to gravity (g). Experiment A used Pasco sensors and Sparkvue software. Experiment B recorded a dropped object with a high-speed camera. Experiment C timed a physics car rolling down an inclined plane attached to ticker tape. The results found g = -9.8 m/s2 for Experiment A, g = -10 m/s2 for Experiment B, and g = -4 m/s2 for Experiment C. Limitations included human error, friction, and sensor accuracy. The purpose was to measure g as accurately as possible through creative experimentation.

This document summarizes experiments conducted to determine the value of gravitational acceleration "g". Two methods were used: dropping various food items from a known height and measuring descent time, and using a pendulum with different string lengths and measuring period. For the dropping method, descent times were recorded and "g" was calculated to be approximately 9.8 m/s^2, showing mass does not affect gravitational acceleration. For the pendulum method, periods were measured for different string lengths and "g" was again found to be approximately 9.8 m/s^2, demonstrating string length does not impact the value of "g". The document concludes the experiments support the hypothesis that gravitational acceleration is constant.
Science academy inquiry 1
The students conducted two experiments to determine the value of the acceleration due to gravity, g. In the first experiment, they measured the time it took a super ball to bounce using a meter stick and digital timer. They calculated g to be approximately 10.5 m/s^2. In their second experiment, they dropped an object from various heights and timed its fall, calculating g to be around 9.5 m/s^2. Their third experiment involved dropping an object from a fixed height of 5.63 meters and timing its fall, determining g to be approximately 10.17 m/s^2.

TIME DRIVEN ACTIVITY BASED COSTING
The document discusses time driven activity based costing (TDABC), a method for calculating the actual costs of logistic activities based on time studies and measurements. It provides examples of calculating order picking costs based on theoretical estimates versus actual recorded times. Implementing a TDABC model gives visibility into costs per activity and customer profitability. The model can be adapted if tariff structures or costs change by developing it with changeable dimensions. Contact information is provided for questions.
