(This technique was used during the Grand Forks flood and the Chernobyl nuclear power plant accident and is often used against forest fires.) The amount of chemical In one of these balls is varied depending on the size of the fire. As a first step in your study. you assume a helicopter is stationary, hovering over a fire. You are to determine if balls of the same size with different Kirgftlhnts of chemical will fall in the same way or differently. The fire department needs actual data. not eory. How do the accelerations of two freely falling objects of different mass compare? co Meter SCk + _ To computer indicate USB port. the scale Prediction: Outline your predictions. explaining each. The explanation part ls important, so think carefully. Exploration: Does the acceleration of a falling body depend on its mass? Perhaps you know the answer. but it was a revolutionary idea when Galileo is said to have dropped two spheres of different masses from the Leaning Tower of Pisa In 1589. Try this out. You should find two balls on the lab table. one ping-pong ball and one golf ball. These are about the same size and shape but have different masses. Perform a simple experiment to see whether these two balls accelerate at the same rate. Did you hear one bang or two
