PHYS 2211: Principles of Physics I

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.

Join us in exploring the concept of significant figures in numerical values. Learn to identify and count significant figures in various numbers, from whole numbers to decimals. Understand the precision and accuracy of your measurements through this engaging video.

Discover the dynamics of a commercial jet takeoff in this video! We explore tire rotation speed, centripetal acceleration, and a bacterium's grip on the rim. Dive into physics and microscopic forces, all while considering weight ratios.

Explore the fascinating world of geosynchronous satellites in this video. Learn how these communication satellites are strategically placed in circular orbits, staying directly over fixed points on the Earth's equator as our planet rotates. We delve into the physics behind these orbits, calculating the speed and acceleration of a satellite in geosynchronous orbit, using the Earth's radius and altitude as reference. Gain a deeper understanding of the science that enables global communications.

Unlock the secrets of calculating electric charge using Coulomb's Law and discover the fascinating world of electrostatic forces. Learn how to determine the charge on two spheres, spaced 20.0 cm apart, and understand the role of elementary particles in this physics tutorial.

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