PHYS 245: Classical Mechanics

Watch as we explore the fascinating world of thermal expansion in this video. We start with a glass filled to the brim with 350.0 mL of water at a scorching 100.0°C, and then witness the magic unfold as the temperature decreases to a cool 20.0°C. But the real question is, how much more water can we add to the glass? Join us to find out!

Explore the concept of capacitance in a spherical capacitor and learn how to calculate it. Discover how to find the plate area for a parallel-plate capacitor with the same capacitance and separation.

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 on the baseball field as we calculate the physics of a ground ball throw to second base. In this video, we determine the distance from the shortstop to the second baseman and the vertical drop of the ball. Explore the principles of projectile motion in sports.

Delve into the physics of high-speed tracks and calculate the radius where drivers experience a 5.5g acceleration, exploring the multiple options and their implications.

Delve into Newton's third law of motion and explore how the choice of the 'system of interest' influences whether force pairs cancel each other out.
