PHYS 151: General Physics I

Join us for a journey with electrons in this video! We explore the motion of an electron through a resistive strip powered by a 12V battery. Discover the electron's direction, work done by the electric field, and the transfer of energy to thermal energy in the strip.

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.

Journey to the outer reaches of our solar system with a captivating exploration of Sedna, the most distant-known object discovered in 2003. This enigmatic celestial body boasts a 1700 km diameter, a 10,500-year orbit around the sun, and a maximum speed of 4.64 km/s. Join us as we delve into the calculations of its elliptical orbit, its minimum speed, and the intriguing variations in its kinetic energy. Uncover the mysteries of Sedna's motion in this educational video.

Explore the fascinating comparison between the acceleration of a motorcycle going from 80 km/h to 90 km/h and a bicycle accelerating from rest to 10 km/h in the same time frame.

Analyze the physics of a falling squirrel, calculating its velocity upon hitting the ground and the deceleration due to limb bending.

Explore the nuances of Newton's third law and learn how the choice of the 'system of interest' influences force pair cancellation.
