PHY 221: General Physics Laboratory I

Learn how to calculate the kinetic energy of a Saturn 5 rocket with an Apollo spacecraft attached using physics principles and formulas. Understand the importance of unit conversion and the work-energy theorem as you plug values into the KE = 1/2 mv² formula. Discover that the kinetic energy for this rocket and spacecraft combo is an astonishing 1.82 x 10¹³ Joules.

Explore the physics of a light-rail commuter train's motion. Understand how to calculate times for acceleration and deceleration using the equations of motion. Dive into the concept of emergency deceleration and its implications.

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.

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

Dive into the world of aviation as we calculate the thrust required for a medium-sized jet to maintain a cruising speed of 230 m/s at a specific altitude. Explore the impact of air density and drag coefficients on aircraft performance.

Explore the fascinating optical phenomena involving a cat, a converging lens, and the creation of virtual and real images.
