PHL 344: Ethical Issues in Health Care

Unpack the concept of normal force on a sports car and its driver atop a hill. Utilize Newton's second law to calculate these forces based on speed and hill curvature. Discover the speed at which the driver feels weightless in the car.

Explore the relative strengths of two fundamental forces, the electromagnetic force and the gravitational force, in this enlightening physics tutorial. Learn about Coulomb's law and Newton's law of gravitation, and uncover the significant difference in their constants that makes the electromagnetic force much more powerful than gravity.

Journey to the outer reaches of our solar system with a captivating exploration of Sedna, the most distant-known object discovered in 2003. This enigmatic celestial body boasts a 1700 km diameter, a 10,500-year orbit around the sun, and a maximum speed of 4.64 km/s. Join us as we delve into the calculations of its elliptical orbit, its minimum speed, and the intriguing variations in its kinetic energy. Uncover the mysteries of Sedna's motion in this educational video.

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.

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.

In this video, we explore the concept of time and distance as we compare two cars traveling at different speeds along a straight highway. We'll calculate when the faster car arrives at a destination 16 km away and find out how far they must travel for it to arrive 15 minutes before the slower car. Join us for an engaging journey through the world of physics and velocity!
