Study Notes
Composition of an Atom
- Atoms consist of three primary subatomic particles: protons, neutrons, and electrons.
- Protons carry a positive charge, neutrons are neutral, and electrons have a negative charge.
Charge Changes with Electron Manipulation
- Adding electrons to an object increases its negative charge.
- Removing electrons from an object decreases its negative charge, potentially leading to a positive overall charge.
Interactions Between Charged Objects
- When two objects with the same charge come into contact, they repel each other.
- When two objects with different charges make contact, they attract each other, potentially leading to charge transfer.
Movement of Subatomic Particles
- Electrons are the only subatomic particles that can move freely from one object to another.
Understanding Friction
- Friction is a force that opposes the relative motion of solid surfaces, fluids, or material elements sliding against each other.
- It can cause charge buildup when electrons are transferred between two surfaces during contact.
