PHYS 71093: College Physics I

Discover how energy conservation principles determine the velocity of a bouncing ball. Relate the ball's height and its potential and kinetic energies. Understand the velocity change upon impact and rebound.

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.

Learn how to determine the hot resistance and current in the electrical system of older cars with a 6.00-V voltage supply.

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.

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.

Illuminate the science of flashlight power! In this video, we explore how a 6V bulb is powered by a 3V battery with an internal resistance. We calculate the power dissipation of the bulb and the terminal voltage of the battery, unraveling the physics of electrical circuits.
