Circuits
What is all matter composed of?
Negative and positive particles.
A wave transports ENERGY and NOT what?
Matter.
The particles that make up all types of matter are in what?
Constant motion.
Why do living organisims need energy?
For growth and improvment!
According to Newton's first law of motion, what will a moving object not acted on by an unbalanced force do?
It will continue to move at a constant velocity.
When the current is higher, are the electrons moving slower or faster?
Faster!
What are the 2 types of Mechanical Waves?
Transverse and Longitudinal.
What do most substances do when heated?
They expand.
What are the 2 types of energy?
Potential and kinetic energy.
Which of Newton's laws states that for every action there is an equal and opposite reaction?
Newton's Third Law.
Why are Electric currents like roller coasters?
They follow a fixed pathway.
What does a Mechanical Wave need to transport energy?
A medium.
What are the most fimiliar states of matter?
Solid, liquid, and gas!
What is another definition of work?
Exerting a force that causes an object to move.
What do balanced forces equal?
They cancel out or equal zero.
What is the path of an electric circuit?
A closed loop.
what is Rarefaction?
Where the wave particles are spread apart.
Which state of matter has the Least amount of kinetic energy?
Solid.
What are examples of Gravitational Potential Energy?
A waterfall, a suspension bridge, and a falling snowflake.
Which of Newton's laws explains inertia?
Newton's first law.
What is voltage?
The potential difference between two points in a circuit.
Which is the top and bottom of the wave?
Crest and trough.
Crest is the top, and trough is the bottom.
Which state of matter has the Most amount of kinetic energy?
Plasma!
What is the Law of Conservation of Energy?
The total amount of energy in a system remain constant or conserved, in other words, Energy cannot be created ordestroyed, but it can be transformed.
According to Newton's 2nd Law, if there is an increase in force, what will happen to the object's acceleration? What is the formula?
The acceleration of the object will increase.
The formula is F=ma.
