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.

Join us in exploring the concept of significant figures in numerical values. Learn to identify and count significant figures in various numbers, from whole numbers to decimals. Understand the precision and accuracy of your measurements through this engaging video.

Uncover the science behind a common sensation - why hot concrete feels hotter than a rug at the same temperature on a scorching summer day. We'll explore the factors at play in this intriguing phenomenon and provide a clear understanding of the science behind it.

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.

In this enlightening video, we unravel the mysteries of electric charges and forces. Discover the fascinating concept of how the separation between two identical tiny spheres, each carrying the same electric charge, influences the force they exert on each other. Will the force double, become one-quarter as large, or remain unchanged? Join us to explore the intriguing world of electrostatics and the principles that govern electric interactions.

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.
