rectilinear motion example particle decelerating
Here we've been given an equation describing the acceleration of a particle. Using only two formulas we can solve this problem: a = dv/dt and v = dx/dt. The problem is solved by pushing through the mathematics and plugging in boundary...

Energy analysis of forced spring mass damper system
Here I derive expressions for the energy added per cycle due to both the harmonic excitation force and the damper. The work done by the spring per cycle = 0. An alternative way to approach this is to find the average power into the system.

The Relationship between Pressure and Volume of a Gas
This is a lecture video explaining the mathematical relationship between the pressure and volume of a gas when it is at a constant temperature and has a fixed mass. The video discusses how the pressure and volume of a gas are inversely...

Why Cant You Use Quantum Mechanics To Communicate Faster Than Light?
The EPR paradox, that we met in a previous video, tells us 2 entangled particles can effect each other no matter now far away they are. But then why cant we use them to send instant messages across the universe? Einsteins relativity...

Italy, Pompeii - Temple of Fortuna Augusta
Researchers believe that the town was founded in the 7th or 6th century BC by the Osci or Oscans. It came under the domination of Rome in the 4th century BC, and was conquered and became a Roman colony in 80 BC after it joined an...

Spying on Synapses - early concept brain research
Signaling across synapses--the tiny gaps between neurons, over a thousand times thinner than a sheet of paper--requires multiple molecules to work together. To learn how neurons communicate, and ensure they pass across the synapses at...
