Geosynchronous Satellite Speed and Acceleration
Want To Learn More? To watch the entire video and ALL of the videos in the series:
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.
Calculating k, Amplitude & Frequency for Fisherman's Scale
Want To Learn More? To watch the entire video and ALL of the videos in the series:
In this video we tackle the real-world physics problem of calculating the spring constant for a fisherman's scale along with the amplitude and frequency of its vibrations when a fish is added. We use Hooke's Law to find the spring constant and then apply oscillation formulas to determine the amplitude and frequency of the fish's vibrations
Newton's Third Law and Force Pairs: System of Interest Impact
Want To Learn More? To watch the entire video and ALL of the videos in the series:
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.
Understanding Volume Units and Cylinder Formula
Want To Learn More? To watch the entire video and ALL of the videos in the series:
In this educational video, we dive into the concept of volume and its units. We explore the correct units for measuring volume and discuss the common misconception that a cylinder's volume is given by ?r^3h. Join us for a comprehensive explanation of the fundamentals of volume measurement and understand why the given formula doesn't hold.
Gravitational Force on the Sun: Earth's Seasonal Variations
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Explore the intriguing interplay of Earth's elliptical orbit, the changing seasons, and the gravitational forces it exerts on the Sun. We'll provide insights into the ratio of these forces and challenge you to consider multiple perspectives on this celestial phenomenon.
