PHYS 142: Elem Gen Physics II

Discover the gravitational forces at play in a triangle of masses in this video. We calculate the net force on each mass and explore how changing the side length impacts these forces. Join us for a gravitational journey through physics.

In this video we tackle the real-world physics problem of calculating the spring constant for a fisherman's scale along with the amplitude and frequency of its vibrations when a fish is added. We use Hooke's Law to find the spring constant and then apply oscillation formulas to determine the amplitude and frequency of the fish's vibrations

Exploring the behavior of oil and water in a U-shaped tube when a barrier is removed. Understand the impact of differing densities on fluid heights. Witness equilibrium scenarios effects of equal densities and the displacement dynamics of lighter liquids.

Unpack the concept of normal force on a sports car and its driver atop a hill. Utilize Newton's second law to calculate these forces based on speed and hill curvature. Discover the speed at which the driver feels weightless in the car.

Unravel the mysteries of rotational symmetry and principal axes in this video. We prove the relationships between the axis of symmetry and principal axes, showcasing the equal principal moments. Join us for an exploration of the fundamental concepts of rigid body dynamics.

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.
