PHYS 212: Essentials of Physics 2

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.

Discover how to calculate rope tension with an object hanging in the center. Understand the relationship between the sag, the weight of the object, and the tension. Convert the result into kilonewtons for easy reference.

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.

Watch as we explore the fascinating world of thermal expansion in this video. We start with a glass filled to the brim with 350.0 mL of water at a scorching 100.0°C, and then witness the magic unfold as the temperature decreases to a cool 20.0°C. But the real question is, how much more water can we add to the glass? Join us to find out!

Explore the intriguing interplay of electric fields and conductors in this video. We examine how the presence of a point charge inside or outside a conductor affects the electric field. Join us to unravel the principles of electrostatics.

Learn how to calculate total displacement when traveling west and south at different speeds and durations. Explore the direction and magnitude of your journey in this informative video.
