Determining Kinetic Friction with a Spring-Loaded Block
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Understand how to determine the coefficient of kinetic friction using a wooden block and a spring. Employing the law of conservation of energy, we use the spring's compression and stretch measurements. Through energy equations and Newton's second law, we deduce that ? equals 0.4.
Shearwater's Return: Average Velocities in Experiment
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Join us as we unravel the incredible journey of a shearwater seabird in an astonishing experiment. This remarkable bird was taken from its nest, flown 5150 kilometers away, and then successfully found its way back home 13.5 days later. We explore the concept of average velocity for both the return flight and the entire episode, shedding light on the bird's navigation prowess. Discover the fascinating world of animal navigation and physics in this captivating video.
Newton's Third Law and Force Pairs: System of Interest Impact
