AP Physics 2
Advanced Placement Physics 2 focusing on fluids, thermodynamics, and modern physics.
Electrostatics and Electricity in Fluids
Charges on the Move
Electricity doesn’t just flow through wires—it can also move through fluids! These are called electrolytes, and their behavior is crucial in batteries and biological systems.
Conductivity in Fluids
When salts dissolve in water, they create ions, allowing electric current to flow. This process powers everything from your smartphone battery to the nerve signals in your body.
Electric Fields in Fluids
The movement of charged particles creates electric fields and can even cause chemical reactions, like in electrolysis.
Real-World Technology
Electrochemistry is the science behind batteries, fuel cells, and even water purification.
Examples
A car battery uses a liquid electrolyte to store and release energy.
Table salt dissolved in water conducts electricity, lighting a small bulb.
In a Nutshell
Fluids can carry electric charge, enabling batteries, nerves, and more.
