PHYS 212: Essentials of Physics II

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.

Learn how to determine the hot resistance and current in the electrical system of older cars with a 6.00-V voltage supply.

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.

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.

Explore the fundamental concept of work in physics and discover the key conditions, including movement, net force, opposing force, and direction, that must be met for work to be accomplished when pushing on an object, such as a rock.
