In this video we tackle the real-world physics problem of calculating the spring constant for a fisherman's scale along with the amplitude and frequency of its vibrations when a fish is added. We use Hooke's Law to find the spring constant and then apply oscillation formulas to determine the amplitude and frequency of the fish's vibrations

Discover how to calculate rope tension with an object hanging in the center. Understand the relationship between the sag, the weight of the object, and the tension. Convert the result into kilonewtons for easy reference.

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.

Discover electromagnetic induction with a rotating wire loop! In this video, we explore how a 12.0-cm-diameter wire loop generates an induced emf when it's aligned with a magnetic field in 0.20 seconds. Dive into the world of electromagnetic phenomena and uncover the average induced emf.
