⇒ Acids taste <em>sour, react with metals, react with carbonates, and turn blue litmus paper red</em>. Bases <em>taste bitter, feel slippery, do not react with carbonates and turn red litmus paper blue</em>.
The study of acids and bases is crucial to chemistry. The Lewis acid/base motif, which broadens the concept of an acid and base beyond H+ and OH- ions, is one of the most relevant theories.
Acids are ionic compounds, which means they have a positive or negative charge. In water, these ionic compounds separate to create hydrogen ions, or H+.
The quantity of H+ ions in the solution determines how strong an acid is. Acid is stronger the more H+ there is. Bases are ionic substances that separate in water to produce the negatively charged hydroxide ion (OH-). The quantity of Hydroxide ions in a base determines its strength (OH-). The strength of the base increases with OH- ion concentration.

The 2nd Law of Motion states acceleration is produced when a n unbalanced force acts on an object (mass) The more mass the object has the more net force has to be used to move it.
Examples:
If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass.
It's easier to push a empty shopping cart then a full one, because the full one has more mass than the empty one. This means more force is required to push the full shopping cart.

The force between charges is proportional to the product of
the two charges. If just one of them is quadrupled, then their
product is also quadrupled, and so is the force between them.
The same identical argument applies to the gravitational force
between masses.
Explanation:
Given:
Δy = 6 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: v
v² = v₀² + 2aΔy
v² = (0 m/s)² + 2 (9.8 m/s²) (6 m)
v ≈ 10.8 m/s
Round as needed.
