I hate those. Might as well read the text all night then sleep in class.

You definetly can't 'make' energy, but yes I agree with your point, mass is energy. However, its more useful to think of mass being converted into energy, as matter has different properties to 'energy' per se

actua;y you can make energy from matter, nless you say they are the same things

you can;t create energy, you convert it.
when you pick up a mass, such as a stone, you are converting 'food energy' into gravititational potential (the energy the stone has because of its height). when you drop the stone, the gravitational potential energy is converted into kinetic energy (energy of movement) as it falls.

Another great clip! I would have loved to be in this course.

Holy shit this guy just bullshits the whole lecture. He takes the simplest types of scientific trivia and spends minutes saying pointless things about them.
Start talking about science already!
The whole lecture can be summarized into 30 minutes of actual information.

So if it takes say, 6 energy to pick something up, how is the energy when you drop it created, is it the same energy as picking it up, and what creates the energy, or what? I'm a little bit confused at how exactly that would work.
