PHY 561: Quantum Mechanics and Modern Physics II

Explore the physics of a tennis ball hitting a wall and its momentum changes. Learn about the original momentum, changes, and the concept of reference objects in this engaging video.

Unlock the secrets of battery performance in this video! We calculate the terminal voltage for a battery with internal resistance, connected in series with resistors of different values. Explore the effects of resistance on voltage in electrical circuits.

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.

Using a cube measuring 28.0 cm per side, we calculate its total electric flux. Through Gauss's law, we determine the box's enclosed charge. The resultant enclosed charge is 9.77 x 10?? C.

Discover the physics behind violin string tension and the angle-dependent force required when pushing it against the neck. Explore how the angle affects the force needed.

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
