PHYS 101: Objects in Motion

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.

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.

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.

Understand how to determine the coefficient of kinetic friction using a wooden block and a spring. Employing the law of conservation of energy, we use the spring's compression and stretch measurements. Through energy equations and Newton's second law, we deduce that ? equals 0.4.

Explore the physics of a tennis ball hitting a wall and its momentum changes. Learn about the original momentum, changes, and the concept of reference objects in this engaging video.
