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.
Calculating Forces & Work for 330-kg Piano on 28° Incline
Want To Learn More? To watch the entire video and ALL of the videos in the series:
In this video we break down a complex physics problem about a 330-kg piano sliding down a 28° incline while a man resists its motion. We meticulously calculate the force exerted by the man work done by various forces including friction and gravity and the net work done on the piano.
The Pricey 'Jenny' Stamp: Calculating Focal Length
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Explore the world of collectible stamps as we delve into the story of the rare 1918 'Jenny' stamp and its astonishing auction price. Join us to learn about the use of a simple magnifying glass to examine this valuable collectible and discover how to calculate its focal length.
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!
