PHYS 211: University Physics: Mechanics

Learn how to determine the hot resistance and current in the electrical system of older cars with a 6.00-V voltage supply.

Estimate a car's initial speed from skid marks using physics principles. Apply Newton's Second Law and equations of motion to deduce the initial velocity. Understand the role of frictional force in car deceleration during accidents.

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!

Explore the dynamics of a bead under constant force. Understand its acceleration, velocity over time, and how to calculate its kinetic energy. Witness the interplay of motion equations and real-world applications in a simple system.

Discover the physics behind the musical notes produced when car tires interact with highway lane dividers. This video explains the "stick-slip friction" phenomenon and its relation to tire vibrations. Learn how analyzing sound frequencies can offer insights into vehicle speeds
