Circuit
Explain the concepts of electric charge and electricity, including how objects become charged and how like and unlike charges interact
Electric charge describes the property of matter that causes it to experience a force when placed in an electromagnetic field.
What is a wave?
A wave is a disturbance that carries energy from one location to another.
What are the defining characteristics of a gas in terms of its shape and volume?
A gas state of matter that lacks a definite shape and volume meaning it conforms to the shape and volume.
How is energy present in our surroundings and what is its role in living organisms?
Energy surrounds us in various forms we receive it as sound,light and wind.
What is weight?
Weight is a measure of the gravitational force acting on an object.
What constitutes all matter and what is the name given to the movement of charged particles?
All matter is made up of all positive and negative particles.
What are two key characteristics of wave propagation?
All waves require energy to travel and waves transport energy not matter.
What is plasma and where is it commonly used?
Plasma is a state of matter that originates as a gas and then becomes ionized.
What is energy?
Energy is the ability to do work.
State Newtons Third Law of Motion?
Newtons Third Law of Motion state that for every action there is an equal and opposite reaction.
What is the source of electrical energy that powers devices like television, computers, and lights
The source of electrical energy for devices such as television, computers, and lights is the movement of electrical charges.
What is a medium as wave propagation?
A medium is a substance or material that transmits waves.
whata re three characteristics of plasma?
They are its particles are electrically charged, it possesses the greatest amount of kinetic energy among the state of matter, and lighting is an example of plasma.
What energy is its SI unit?
The SI unit for energy is the Joule (J) which is the same unit used for work.
How can momentum be defined?
Momentum can be defined as "mass in motion".
What is the relationship between the magnitude of electric current and the speed of moving electric charges?
A higher electric current corresponds to faster moving electric charges such as electrons.
What are the characteristics that define mechanical waves?
Mechanical waves require a medium to transport their energy.
What are the three main types of phase changes?
Liquid to gas
Gas to liquid
Solid to gas
What is potential energy?
Potential energy is stored energy that an object has due to its position.
Do objects at rest have momentum?
No.
How do electric circuits control the movement of electric current and what is the characteristic shape of their path?
Electric circuits control the movement of electric current by providing defined paths of electrons to follow.
What are some examples of transverse waves?
Ocean waves, ripples on a water surface, vibrating guitar strings, and electromagnetic waves.
What are the four fundamental states of matter?
solid, liquid, gas, and plasma.
How does an objects speed and mass affect its kinetic energy?
An object's kinetic energy increases with both its speed and mass.
What does the Law of Conservation of Momentum state?
The Law of Conservation of Momentum states that the total amount of Momentum is a closed system remains constant.
