Solutions
What is a solute?
The chemical or substance found in smaller amounts of a solution.
What is an acid?
Chemical compounds which are proton donors
What is a reference point?
A place or object used to help determine the movement of another object
What is force?
A push or a pull exerted from one object onto a second object.
What is friction?
The force that two surfaces exert on each other when they run each each other.
What is a solution?
A mixture in which a solute is completely mixed into a solvent.
What is a base?
Chemical compounds which are proton receivers
What is relative motion?
When one object appears to be moving while another appears stationary.
What is the weight equation?
w= mg
What is static friction?
Friction which acts in the opposite direction to the intended motion.
What is an example of an ionic solution?
Salt Water
What is an example of an acid?
Lemons
What is velocity?
Speed with a direction.
What is net force?
The combination of all forces working on an object.
What is sledding friction?
When two surfaces slide over each other.
What is the difference between a saturated solution and an unsaturated solution?
Saturated solution: max amount of solute is dissolved in it; unsaturated solution: still capable of dissolving more solute in it.
What is an example of a base?
Baking Soda
What is acceleration?
The rate at which velocity changes
What is the force equation?
F = ma
What is an example of rolling friction?
A tire rolling on the street.
What is the difference between concentration and solubility?
Concentration: amount dissolved; Solubility: how it dissolves
What are the four properties of an acid?
Turns litmus paper red
Reacts with metals and carbonates
Tastes sour
Reacts with an indicator
What is the acceleration equation?
a = V/t
What is the gravitational constant?
g = 9.8 m/s2
A rock slide begins on a mountain side. What forces and frictions are at work?
Force: gravity and whatever item started the rock slide.
Friction: rolling and sliding friction, even a little bit of static friction.
