PHYS 250: Matter and Energy

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.

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

Uncover the methodology behind determining an unknown light's wavelength using the double slit experiment. Understand how fringe spacings relate to the light's properties. Find out the significance of second-order fringes and their measurements.

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.

Dive into the thrilling world of physics and surfing as we explore the angle of inclination of a wave's face. Discover how a surfer accelerates down a wave with an acceleration of 3.25 m/s² while ignoring friction. Join us for an engaging and educational explanation of this exciting phenomenon.
