Properties of Matter
Anything that has mass and takes up space (has volume)
What is matter?
This is the center of an atom
What is nucleus?
A change in an object's velocity over time.
What is acceleration?
A force that opposes motion
What is friction?
This word means the ability to do work.
The ratio of a substance's mass to it's volume
What is density?
This subatomic particle flies around the nucleus in various shells.
What is electron?
A point against which motion is measured
What is a reference point?
Friction that opposes the initiation of motion
What is static friction?
What is potential energy?
The smallest chemical unit of an element
What is an atom?
This number is the total number of protons, neutrons, and electrons an atom usually has.
What is atomic number?
This type of measurement only contains a magnitude (number) and does not contain directional information
What is scalar quantity?
For every action there is an equal and opposite reaction. This is stated in which of who's laws?
Newton's Third Law of Motion
The product of a force applied in the direction of motion of an object, and the distance the object moves, is known as this.
What is work?
In sweet tea, this is the substance known as the "solute".
What is sugar?
(or, what are tea leaves?)
The second electron shell can hold this many electrons.
What is eight?
A physical measurement that contains both magnitude (number) and directional information
What is vector quantity?
The motion of an object when it is falling solely under the influence of gravity.
What is free fall?
The mechanical advantage describes how much easier this item makes work.
What is a machine?
The phase change in which gas changes directly to a solid without first going through the liquid phase
What is deposition?
With an atomic number of 20, calcium has this many electron shells.
What is 4?
The distance an object travels plus the direction from the starting point
What is displacement?
The force exerted by an object is equal to the mass of that object times its acceleration (F=m x a). This is stated in which of who's laws?
Newton's Second Law of Motion
The amount of work done each second.
What is power?
