What is electric charge (q)?
The fundamental property of matter that causes electrical phenomena.
What is electrostatic force (Fe)?
The force between charged objects.
What is the conservation of charge?
The total electric charge in an isolated system remains constant.
Define displacement (Δx).
Change in position. It's a vector!
Define velocity (v).
Rate of change of displacement. Also a vector!
Define acceleration (a).
Rate of change of velocity. A vector!
State Newton's 1st Law of Motion.
An object at rest stays at rest, and an object in motion stays in motion with the same velocity unless acted upon by a net force.
State Newton's 2nd Law of Motion.
F = ma (Force equals mass times acceleration).
State Newton's 3rd Law of Motion.
For every action, there is an equal and opposite reaction.
What are the differences between horizontal and vertical motion in projectile motion?
Horizontal Motion: Constant velocity (no acceleration). | Vertical Motion: Constant acceleration due to gravity (g = 9.8 m/s²).
What is the effect of like charges being near each other?
They repel each other.
What is the effect of opposite charges being near each other?
They attract each other.
What happens when a net force acts on an object?
The object accelerates in the direction of the force.
