PHYS 17200: Modern Mechanics

oin us as we delve into the intriguing world of subatomic particles! In this video, we'll decipher the composition of a system containing 1525 electrons and protons with a net charge of -5.456 x 10^-17 C. Discover the precise number of electrons and calculate the total mass of this dynamic system. Unlock the secrets of particle physics with us!

Exploring the behavior of oil and water in a U-shaped tube when a barrier is removed. Understand the impact of differing densities on fluid heights. Witness equilibrium scenarios effects of equal densities and the displacement dynamics of lighter liquids.

In an elevator ascending, an occupant drops a coin, which accelerates at a different rate than expected. This reveals the elevator's own acceleration towards the Earth. By analyzing forces and tensions, we determine the cable's tension to be 16000 N.

Step into the thrilling world of amusement park divers as we explore the physics behind their jaw-dropping stunts. Diving from a platform 21.3 meters (70 feet) above a pool of water, we investigate the announcer's claim that divers enter the water at a speed of 56 miles per hour (25 meters per second). We'll also uncover the possibility of divers leaping directly upward to achieve a specific water entry speed and examine the physical feasibility of such a feat. Join us for an educational journey

Unpack the concept of normal force on a sports car and its driver atop a hill. Utilize Newton's second law to calculate these forces based on speed and hill curvature. Discover the speed at which the driver feels weightless in the car.
