PHYS 91: Physics I

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.

Uncover the fascinating science behind peephole lenses, including the principles of light refraction and observer positioning that allow for an extensive field of vision through a hotel room door.

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

Explore the physics behind calculating the velocity of pebbles thrown by Romeo to hit Juliet's window with only a horizontal component.

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.
