Dory, Marlin, and Nemo are on their way back to their home when fisherman in the area scoop up many fish, including Dory. The boat starts to hoist the net and the fish out of the water. Nemo tells his father, Marlin, that the only way to save Dory is for all of the fish in the net to swim down. After all of the fish swim down together, they break the net and free themselves and Dory.
Phil explains and illustrates Newton's first law of motion and angular momentum using a 20 kg weight. In the experiment, they are having trouble spinning the weight fast enough. They eventually spin it fast enough that it doesn't topple over immediately.
Hazel Fanny the Science Granny demonstrates balanced and unbalanced forces using a game of tug of war. When forces are in balance, they are equal, and no movement occurs. When forces are unbalanced, they are unequal, and movement occurs.
A fight breaks out, and Isaac Newton watches the quarrel and draws conclusions about forces based on his observations. Each boy is considered a mass, and each of their pushes is a force. At the end of the scuffle, Newton labels his conclusions "The Laws of Motion." This clip is an excellent depiction of Newton's laws of motion in a real-world context.
