|
What is Newton's 1st Law?
Inertia! "An object at rest stays at rest or an object in motion stays in motion unless acted upon by an unbalanced force"
|
Properties can be defined as ...
Physical and Chemical
|
What are 2 types of mixtures?
Heterogeneous and Homogeneous
|
Who is the person that first developed the idea of atoms as the smallest possible bit of matter?
Democritus
|
What is motion?
It occurs when an object changes position relative to a reference point
|
What is Newton's 2nd Law?
The greater the force, the greater the acceleration. The greater the mass, the greater
|
What are physical properties?
Properties that are observable, measurable, and will keep the same composition.
|
What is a mixture?
Two or more materials mixed and are easily separated.
|
Where does the word atom come from?
The Greek word atomos, meaning invisible
|
What is displacement?
Distance and direction of an object's change in position from the starting point
|
What is Newton's 3rd Law?
For every action force, there is an equal and opposite reaction force.
|
What are density and its formula?
The amount of matter in a given volume. Mass divided by volume
|
What is a solution?
Two or more materials mixed; are difficult or impossible to separate.
|
Who developed the atomic theory?
John Dalton
|
What is speed and its formula for average speed?
The distance an object travels per unit/time rate of change in position. The formula is distance divided by time.
|
What is inertia?
A property of matter. The tendency of an object to resist any change in its motion.
|
What is conductivity?
The ability to conduct or transmit heat, electricity, or sound
|
What are solvents?
The liquid that the solute dissolve in
|
What did Niels Bohr discover?
He discovered that electrons traveled in energy levels around the nucleus.
