PHYS 71115: University Physics II

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.

Uncover the secrets of watch crystals in this video! We convert the frequency of a quartz crystal used in electric watches into its period. Join us to explore the principles of timekeeping and crystal oscillations.

Discover the significance of models in the fascinating realms of relativity and quantum mechanics, where conditions defy our everyday experience. Explore the concept of a model and its role in understanding these complex theories.

Explore the profound link between these two fundamental concepts in physics, and understand how they relate through the Work-Energy Theorem.

Join us in a lunar leap! We estimate how gravity affects jumping distance on the Moon compared to Earth, with the same takeoff speed and angle. Explore the moon's reduced gravity and its impact on human capabilities.

Join us for an engaging exploration of projectile motion as we dissect a fascinating scenario. We delve into the physics of a projectile fired with an initial speed of 36.6 m/s at an angle of 42.2° above the horizontal on a flat firing range. Discover how to determine the maximum height, total time in the air, total horizontal distance covered (range), and the speed of the projectile 1.50 seconds after firing. This video will demystify the dynamics of projectiles in a clear and educational manne
