PHYS 124: Physics 2

Learn how to compute the displacement of a ball rolling off a table using calculus. Through the integration of velocity over a specific time interval, determine the ball's position. Uncover the mathematics behind real-world motion scenarios.

Explore the intricate dynamics of an L-C circuit as we analyze voltage current and energy transitions between a 60.0 millihenry inductor and a 250 microfarad capacitor. Understand the principles of energy transfer and storage in this system. Uncover key insights from calculations on capacitor charges and inductor energies at specific circuit conditions.

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.

Discover the math behind car spring oscillations when driving over bumps. Understand how a car's weight and driver affect the spring constant and resulting frequency. Grasp the interplay of forces and how they dictate harmonic motion.

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.

Join us for a dramatic river rescue mission! In this video, we solve the problem of how a rescue team can reach a child in danger of drowning in a fast-flowing river. We calculate the angle from the shore for their pilot to approach the child directly, considering the river's current and the boat's speed. Explore the principles of vector addition and save lives!
