Khan Academy: Centripetal Acceleration: Loop De Loop Answer Part 2

Take a look at acceleration within the context of automotive technology. They vary the mass on a toy car and run it down a ramp, exploring Newton's second law of motion. Though this is a classic lab activity, you will appreciate the...

Figuring out the minimum speed at the top of the loop de loop to stay on the track

This video asks students to find the minimum speed necessary to complete the loop de loop. [3:01]

This video builds off of part 1 where the radius of the circle traveled by the proton calculated by using the formula for centripetal acceleration. [10:39]

A video proving that a = v^2/r in regards to centripetal acceleration. [14:22]

This video lecture will use the Universal Law of Gravitation to calculate the acceleration due to gravity at the surface of the Earth. Video will then calculate the space station's acceleration due to gravity. [10:12]

Figure out how all of those physiology terms - end-systolic, end-diastolic, pulse pressure, stroke volume, and ejection fraction - can be easily understood using the pressure-volume loop. Rishi is a pediatric infectious disease physician...

Understand LaPlace's law to see the effect that pressure, radius, and wall thickness each have on the "wall stress" in the left ventricle to answer the question of why the heart never gets a rip or tear. Rishi is a pediatric infectious...

Understand what is happening at the cellular level to cause two identical left ventricular volumes to have such different pressures! Rishi is a pediatric infectious disease physician and works at Khan Academy.

Ever wonder exactly how the left ventricle's pressure changes over time? Find out in this color-coded video! Rishi is a pediatric infectious disease physician and works at Khan Academy. [10:51]
