What happens to the electrostatic force if the distance between two charges is doubled?
The electrostatic force decreases by a factor of four.
What happens to the electrostatic force if the magnitude of one charge is doubled?
The electrostatic force doubles.
What happens when the net force on an object is zero?
The object is in equilibrium, either at rest or moving at a constant velocity.
What happens when a positive charge is placed in an electric field?
The charge experiences a force in the direction of the electric field, causing it to accelerate in that direction (if free to move).
What happens when a negative charge is placed in an electric field?
The charge experiences a force opposite to the direction of the electric field, causing it to accelerate in the opposite direction (if free to move).
What are the key differences between electric force and gravitational force?
Electric Force: Can be attractive or repulsive, depends on charge, much stronger at atomic level. | Gravitational Force: Always attractive, depends on mass, weaker at atomic level.
Compare the forces experienced by positive and negative charges in an electric field.
Positive Charge: Experiences force in the direction of the electric field. | Negative Charge: Experiences force opposite to the direction of the electric field.
In a Free-Body Diagram, what do the arrows represent?
Arrows represent forces acting on the object. The length indicates magnitude, and the direction indicates the force's direction.
In a Free-Body Diagram, what does the dot or shape represent?
The dot or shape represents the isolated object being analyzed.
