PH 312: HIV/AIDS in Modern Society

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.

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.

In this enlightening video, we unravel the mysteries of electric charges and forces. Discover the fascinating concept of how the separation between two identical tiny spheres, each carrying the same electric charge, influences the force they exert on each other. Will the force double, become one-quarter as large, or remain unchanged? Join us to explore the intriguing world of electrostatics and the principles that govern electric interactions.

Learn how to calculate the kinetic energy of a Saturn 5 rocket with an Apollo spacecraft attached using physics principles and formulas. Understand the importance of unit conversion and the work-energy theorem as you plug values into the KE = 1/2 mv² formula. Discover that the kinetic energy for this rocket and spacecraft combo is an astonishing 1.82 x 10¹³ Joules.

Delve into the physics of high-speed tracks and calculate the radius where drivers experience a 5.5g acceleration, exploring the multiple options and their implications.

Explore the physics of a car's quick deceleration, including angular acceleration, revolutions, time, distance, initial velocity, and the realism of the scenario.
