Science 9 - Q1

This subject is covered by the lessons, consisting of Electricity, Ohm's Law, and Law of Resistor

Thales of Milethus

He is studied such ability of amber

William Gilbert

He is known as the discoverer of rubber materials

Static Electricity

A type of electricity that has buildup of an electric charge on the surface of an object

Electrostatics

It is a branch of physics that is described all charged bodies at rest

Electric charge

A physical property of matter, causing it to experience a force

One-Fluid Theory

A theory that is proposed by Benjamin Franklin by 1741

Two-fluid Theory

a theory that is proposed by Charles Du Fay

Coloumb’s law and electric force

Proposed by Charles Augustin de Coloumb

Alternating (AC) Battery

A type of battery that is flowed by back-and-forth movement of electrons, and is presented through sinusoidal / sine wave

Direct (DC) Battery

A type of battery that is directly flowed through a conductor; and is classified into three: the voltage, current, and resistance — a triangle of Ohm’s Law, usually used to solve and find them

Insulator

a substance that allows the electrical charge to flow easily

Insulator

A substance that is opposed to conductor, and cannot be flowed easily

George Simon Ohm

a German physicist who proposed the Ohm’s law, and a triangle of this law as well.

Series circuit

A circuit that is directly connected more than one load

Parallel Circuit

A circuit that has such loads / bulbs, but it is flowed side-by-side or independently has a designated switch or breaker

Electric circuit

A general circuit that is combined a source of power and wire

Load, Electricity, Conductor

___, ____, and ____, are the parts of electric circuit

Representation of resistor

Representation of cell

Representation of battery

Representations of capacitor

V = IR / Voltage = Current x Resistance

Formula of voltage

I = V/R or Current = Voltage over Resistance

Formula of current

R = V over I or Resistance = Voltage over Current

formula of resistance

Acceleration

is a fundamental concept

in physics that describes how the

velocity of an object changes over time. It also pertains to a vector quantity, meaning it

has both magnitude and direction.

formula for acceleration

m/s²

unit for acceleration

m/s

unit for velocity

Positive acceleration

This acceleration occurs when an object speeds up.

Negative acceleration or Decceleration

This acceleration occurs when an object

slows down. It has another term aside from this acceleration.

Uniform acceleration

means the rate of acceleration stays constant,

such as an object in free fall near Earth's surface. It accelerates at approximately 9.8 m/s² due to gravity.

Zero acceleration

occurs when an object's velocity remains constant

over time — that is, there is no change in speed or direction.

formula for the following if at rest

formula with initial velocity

Newton’s Law of Motion

. A set of three fundamental principles that describe the relationship between the motion of an object and the forces acting upon it.

. It was formulated by Sir Isaac Newton in 17th century

Law of Inertia

This law states that an object at rest will remain at

rest, and an object in motion will continue to

move in a straight line at a constant speed

unless acted upon by a net external force.

Law of Acceleration

This law defines the relationship between force, motion, mass, and this law.

Law of Interaction / Action and Reaction

This law states when one object exerts a force on another object, another object exerts, too, a force of equal strength.

Vector

direction and magnitude

Scalor

magnitude only
