1. Rub two neutral objects together. 2. Electrons transfer from one object to the other. 3. One object becomes positively charged, and the other becomes negatively charged.

1. Bring a charged object into contact with a neutral object. 2. Charge transfers between the objects. 3. Both objects end up with the same type of charge.

1. Bring a charged object near a neutral object (no contact). 2. Polarization occurs within the neutral object. 3. Remove the charged object. 4. The neutral object returns to its neutral state.

1. Bring a charged object near a neutral object (no contact). 2. Polarization occurs within the neutral object. 3. Ground the neutral object, allowing charge to flow in or out. 4. Remove the ground. 5. Remove the charged object. 6. The neutral object is left with a charge opposite to the original charged object.

1. Calculate the electrostatic force between each pair of charges using Coulomb's Law. 2. Determine the direction of each force (attractive or repulsive). 3. Resolve each force into its x and y components. 4. Sum the x-components and y-components separately to find the net x and y components of the force. 5. Calculate the magnitude and direction of the net force using vector addition.

Conductors: Allow free movement of charge, typically metals | Insulators: Restrict charge movement, typically rubber, plastic, etc.

Contact: Requires physical touch, results in the same charge | Induction: No physical touch, can result in the opposite charge (if grounded)

The electrons in the conductor will be attracted to the positive charge, causing polarization (separation of charge).

They repel each other with a force described by Coulomb's Law.

It allows charge to flow either into or out of the object, resulting in a permanent charge opposite to that of the inducing object.

The electrostatic force between them decreases (inversely proportional to the square of the distance).

The electrostatic force between them increases (directly proportional to the product of the charges).
