Unravel the mysteries of rotational symmetry and principal axes in this video. We prove the relationships between the axis of symmetry and principal axes, showcasing the equal principal moments. Join us for an exploration of the fundamental concepts of rigid body dynamics.
Time and Distance: Comparing 85 km/h and 115 km/h Cars
Want To Learn More? To watch the entire video and ALL of the videos in the series:
In this video, we explore the concept of time and distance as we compare two cars traveling at different speeds along a straight highway. We'll calculate when the faster car arrives at a destination 16 km away and find out how far they must travel for it to arrive 15 minutes before the slower car. Join us for an engaging journey through the world of physics and velocity!
Electromagnetic vs. Gravitational Forces: A Comparative Analysis
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Explore the relative strengths of two fundamental forces, the electromagnetic force and the gravitational force, in this enlightening physics tutorial. Learn about Coulomb's law and Newton's law of gravitation, and uncover the significant difference in their constants that makes the electromagnetic force much more powerful than gravity.
Warm Hands by Friction: Temperature Increase Calculation
