Did your experiment support or disprove your hypothesis? What’s Going On? 8 m/sec2) and L is the length of the pendulum in meters. Therefore, the length of time a pendulum takes to make one swing depends on the length of the pendulum and the pull of gravity. A longer string will result in a longer period, while a shorter string produces a shorter period. The mass of the pendulum bob is not included in the equation because it is not relevant to the swing of a pendulum. Newton’s second law of motion states that every object in motion will continue in motion until acted upon by a force.

Bottling companies pressurize beverages so they can easily introduce large volumes of carbon dioxide. Some types of carbonated beverages contain more carbon dioxide than others. Seltzer waters and soft drinks with artificial sweeteners tend to contain more carbonation than sugar-containing soft drinks. Additional carbon dioxide simply produces more carbonic acid, giving the drink its desired taste. 34 PHYSICAL SCIENCE experiments increase pressure normal pressure high pressure gas dissolved gas Figure 2 Figure 2 A fluid holds more dissolved gas when pressure is high.
