PHL 215: Thermodynamics and Modern Physics

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.

Discover how energy conservation principles determine the velocity of a bouncing ball. Relate the ball's height and its potential and kinetic energies. Understand the velocity change upon impact and rebound.

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.

Join us on the baseball field as we calculate the physics of a ground ball throw to second base. In this video, we determine the distance from the shortstop to the second baseman and the vertical drop of the ball. Explore the principles of projectile motion in sports.

Join us on an exciting lunar adventure as we explore the descent of a lunar lander towards the moon's surface. We'll unravel the physics behind its journey using the equation y(t) = b - ct + dt^2, and answer questions about the lander's initial and final velocities. Get ready to explore the dynamics of space exploration and lunar landings in this informative video!
