PHYS 150: Physics

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.

Unlock the secrets of battery performance in this video! We calculate the terminal voltage for a battery with internal resistance, connected in series with resistors of different values. Explore the effects of resistance on voltage in electrical circuits.

Join us as we delve into the physics of a monkey and her cart, complete with a spring. Witness the intriguing change in maximum speed when the monkey picks up a cantaloupe. Learn how mass and vibrations affect the outcome.

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.

Join us in exploring the fascinating world of vectors and vector addition. In this video, we answer a fundamental question: Can two vectors with different magnitudes ever sum to zero? Delve into the principles of vector mathematics and discover the insights behind this intriguing concept. Tune in for a mind-expanding journey through the world of mathematics!
