Question

Omar compares the body shapes of different species to understand what helps them move. He has read that when monkeys swing from tree to tree, they move like pendulums. When they swing from one branch immediately to another, they swing slowly. But, when they prepare to let go and fly to a branch a greater distance away, they swing quickly. Omar wants to figure out what basic variables affect their pendulum motion.

Omar designs an experiment to determine what affects the time it takes for a pendulum to oscillate (swing back and forth one time). In his experiment, three independent variables a
