this person is credited with discovering that lightning is an electrical phoenomena
Ben Franklin (I h8 u)
The Greek word "atom" means what?
indivisible
What is the first law of motion?
An object in motion will stay in motion unless acted upon by an external force.
what is this law: Fe=k q1q2/r^2, and what does it describe.
Coulomb's Law, describes the electrostatic force between two charged particles, stating that the force is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
What is a scalar field?
Has magnitude but no direction.
ex. time
Who dubbed the term electric force?
William Gilbert
What is the nucleus of the Atom composed of?
Neutrons and Protons
What is the second law of motion?
F=ma
F=ma describes what?
This equation means that a greater force is required to accelerate a more massive object, and for a given force, a more massive object will accelerate less than a less massive one.
What is a vector?
Has magnitude and direction.
Who is credited with creating the laws that are the fundamentals of physics.
Newton
What does the resource guide equate to planets in a solar system.
electrons
What is the third law of motion?
Every action has its equal and opposite reaction?
FG=G m1m2/r^2
What is inverse square law?
The further away something gets from the electric field, the weaker it gets by 1/x2
6.67x10^-11 is whos constant?
Newtons
Electricity primarily includes the movement of what? (ts free points)
Electrons
If a ball is rolled across a flat surface, what slows it?
Friction!
What is the equation for Gravitational Field?
Fg=mg
What are the 4 fundamental forces of the universe?
Electricity, weak nuclear force, strong nuclear force, gravity.
Who created a law by observing a torsion balance?
Charles Coulomb
What does the strong and weak nuclear force do? (no half credit).
Strong: Keeps protons and neutrons in the nucleus.
weak:Transforms particles into other particles and is primarily involved in radioactive decay
The strength of force is measured in what?
Newtons!!!
Einitial =Efinal describes what?
Conservation of energy
What is a dipole?
2 opposite charges placed next to each other.
