PHY 2020: Introduction to Physics

Discover the gravitational forces at play in a triangle of masses in this video. We calculate the net force on each mass and explore how changing the side length impacts these forces. Join us for a gravitational journey through physics.

Discover electromagnetic induction with a rotating wire loop! In this video, we explore how a 12.0-cm-diameter wire loop generates an induced emf when it's aligned with a magnetic field in 0.20 seconds. Dive into the world of electromagnetic phenomena and uncover the average induced emf.

Step into the showroom as we explore the intriguing connection between rug dimensions and area. Learn whether a rug being twice as long as another implies its area is also doubled. Join us for a comprehensive explanation of this geometric concept.

Explore the physics behind a water-skier accelerating from an initial speed to a faster one. Learn how to calculate the work done using the change in kinetic energy. Understand the principle of energy conservation through real-world examples.

Join us to unravel the mystery of oscillations! In this video, we'll determine the period of a mass oscillating with a 0.2 m displacement and 1.2 m/s maximum speed. Explore the physics behind periodic motion and discover the key to calculating its period. Dive into the world of harmonic motion with us!

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.
