PHYSICS 113: PHYSICS 113

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

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

In this video we break down a complex physics problem about a 330-kg piano sliding down a 28° incline while a man resists its motion. We meticulously calculate the force exerted by the man work done by various forces including friction and gravity and the net work done on the piano.

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 for a dramatic river rescue mission! In this video, we solve the problem of how a rescue team can reach a child in danger of drowning in a fast-flowing river. We calculate the angle from the shore for their pilot to approach the child directly, considering the river's current and the boat's speed. Explore the principles of vector addition and save lives!

Uncover the secrets of watch crystals in this video! We convert the frequency of a quartz crystal used in electric watches into its period. Join us to explore the principles of timekeeping and crystal oscillations.
