Circuit Diagrams for drawing circuit schematics or maps

Use the below symbols when drawing a circuit.  Remember there is a difference between a parallel circuit and a series circuit.  A series circuit is when the entire circuit is in one loop.  A parallel circuit is a closed path of electricity where there are multiple, independent paths for the electricity to flow through.

Electricity Numbers you need to know (pt 1)

The charge of an electron is              q = – 1.6 x 10-19C

The charge of a proton is                  q = + 1.6 x 10-19C        

The strength of the electric field         k = 8.9 x 109 Nm2 /C2

The strength of gravity                  G = 6.67 x10-11 Nm2 /kg2

The mass of an electron                 me =  9 x 10-31 kg

The mass of a proton                     mp =  2 x 10-27 kg

Recoil Videos, Hancock video and Hancock Work Sheet





Recoil Video - Look for how Momentum is Conserved;  You can think of this also as what not to do when firing a gun.

Watch the below Hancock Video and explore what happens.   Can you explain using the Law of Conservation of Momentum why or why not what you see is possible?  After watching the video, fill out the attached worksheet.  Link Below.
