Physical Science:
Catapult Experiment -
Will continued with his catapult experiment. First we reviewed the scientific process he used on Monday, to determine the force the catapult exerted on the ball. He had concluded collecting data by recording the mass of the ball. He conducted his analysis of the data, and applied the correct formula to find the speed of the ball from the distance and time. He also used the formula for finding acceleration from the speed at the start of the experiment and the speed at the end of the experiment. He then used Newton’s second law (F=M*A) to find the force applied to the ball. He then recorded his conclusions in relation to his hypothesis and then wrote his discussion of the process. We spent some time imagining how his conclusions on the force of a catapult, benefited those who used catapults.
