PHYS 101: Objects in Motion

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.

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.

In this video we break down a complex physics problem about a 330-kg piano sliding down a 28° incline while a man resists its motion. We meticulously calculate the force exerted by the man work done by various forces including friction and gravity and the net work done on the piano.

Delve into the physics of high-speed tracks and calculate the radius where drivers experience a 5.5g acceleration, exploring the multiple options and their implications.

Embark on a celestial journey! In this video, we calculate the altitude above a distant planet's surface where a starship orbits. Discover how astronauts experience reduced free-fall acceleration and the fascinating dynamics of space travel.

Dive into the physics of cliff jumping as we analyze the splashdown speeds of two adventurous youngsters. Explore the factors that determine their speeds and choose the best explanation among the options provided.
