PHYS 111: General Physics I (PHY 111)

Discover the physics behind the angle formed by loosely hanging hand straps on a streetcar negotiating a curved turn.

Discover the math behind car spring oscillations when driving over bumps. Understand how a car's weight and driver affect the spring constant and resulting frequency. Grasp the interplay of forces and how they dictate harmonic motion.

Discover the perfect golf shot! We calculate the height of the tallest tree a golf ball must clear to achieve the longest possible hole-in-one. Explore the physics and precision of golf's ultimate achievement.

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.

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 physics behind a water-skier accelerating from an initial speed to a faster one. Learn how to calculate the work done using the change in kinetic energy. Understand the principle of energy conservation through real-world examples.
