Your first experiments in physics will be with the pendulum. Read and study the information on pendulums, do the experiments, and then answer the questions. The language of physics is mathematics - algebra, trigonometry and calculus. You may need a refresher on some trigonometry. You will find that here as well. Finally, you can do some more experiments with the pendulum by using the simulation from PhET. Find out how the mass, length and angle affect the period of a pendulum. Finally, determine the acceleration due to gravity (g) on Planet X. For multiple pendulum lengths, take corresponding photogate timer measurements and graph L vs T2. Compute g on Planet X from the slope of the line.
