PHYS 1010: Current Topics in Modern Physics

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.

Explore how a mass spectrometer works by analyzing an ion's path through the device. Understand the relationship between electric and magnetic fields in determining the ion's trajectory. Learn to compute the radius of an ion's path within the mass spectrometer.

Learn how to convert between radians and degrees for various angle measurements, expanding your understanding of angular units.

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.

Uncover the fascinating science behind peephole lenses, including the principles of light refraction and observer positioning that allow for an extensive field of vision through a hotel room door.

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!
