PHYS 185: Physics

In this enlightening video, we unravel the mysteries of electric charges and forces. Discover the fascinating concept of how the separation between two identical tiny spheres, each carrying the same electric charge, influences the force they exert on each other. Will the force double, become one-quarter as large, or remain unchanged? Join us to explore the intriguing world of electrostatics and the principles that govern electric interactions.

Discover the impact of a 0.09-N thrust engine on a 480 kg spacecraft's speed during 1 week of maximum power operation. Uncover the assumptions involved in this space physics scenario.

Analyze the physics of a falling squirrel, calculating its velocity upon hitting the ground and the deceleration due to limb bending.

Explore the dynamics of a bead under constant force. Understand its acceleration, velocity over time, and how to calculate its kinetic energy. Witness the interplay of motion equations and real-world applications in a simple system.

Join us for a journey with electrons in this video! We explore the motion of an electron through a resistive strip powered by a 12V battery. Discover the electron's direction, work done by the electric field, and the transfer of energy to thermal energy in the strip.

Explore the physics of a tennis ball hitting a wall and its momentum changes. Learn about the original momentum, changes, and the concept of reference objects in this engaging video.
