Classifying Matter
Anything that has volume and mass
Matter
---> O --->
20N 15N
35N Right
A change in motion caused by an unbalanced force acting on an object; includes increasing speed, decreasing speed, or a change in direction
Acceleration
A compound that tastes sour and has a lower pH than water
Acid
Fe
Ne
Mg
Elements
Has ingredients combined but not uniformly mixed together
Heterogeneous Mixture
<------ O ----->
27N 14N
13N Left
The amount of force applied to an object determines how much it will accelerate. The greater the mass the more force needed.
Newton's 2nd Law
The Left and Right side of a chemical equation
Reactants and Products
A change that involves one substance being pulled apart or combined with another substance to form a completely different substance or substances
Chemical Change
Formed when two or more different elements are chemically bonded
Compound
Formula for finding Acceleration
a = f/m
The tendency of an object to remain still or continue moving unless force is applied
Inertia
The ability of a liquid to resist a downward force through its surface
Surface Tension
When the sum of the forces acting on an object are unequal
Unbalanced Force
A pure substance made of the same types of atoms throughout
Elements
Force 15N
Mass 1.25kg
Acceleration ?
12 m/s2
a car comes to a sudden stop, and you continue forward until the seatbelt causes you to stop.
Newton's First Law
A scale ranging from 0–14 that measures how acidic or basic a solution is
pH Scale
NaOCl + 2HCl → NaCl + H2O + Cl2
If the reactants have a mass of 57g, what should be the mass of the products
57g
NaCl
H2O
NaOH
Compound
Force 11N
Mass 1.376 kg
Acceleration ?
7.99 m/s2
a car hits a curb, and you apply a force on the seatbelt, and the seatbelt applies the same amount of force back on you.
Newton's Third Law
A solution with a pH of 7
Neutral Solution
6CO2 + 6H2O → C6H12O6 + 6O2
