PHYS 161: General Astronomy 1

Discover the perfect golf shot! We calculate the height of the tallest tree a golf ball must clear to achieve the longest possible hole-in-one. Explore the physics and precision of golf's ultimate achievement.

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.

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!

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.

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.
