Is a mixture containing small, undissolved particles that do not settle out.

Is a mixture containing a solvent and at least one solute and has the same properties throughout.

Are the three types of mixtures:

Are the two parts of a solution:

Solubility is a measure of how much solute can dissolve in a solvent.

If a 100-grams solution contains 10 grams of solute, What is its concentration?

Acids have a sweet taste.

Bases feels slippery.

In the pH scale the substances with pH=3 are:

The reaction between an acid and a base is called:

An object is in motion if its position changes relative to another object.

Is a place or object used for comparison to determine if something is in motion.

Speed is a vector.

Velocity require magnitude and direction.

1. A race’s car velocity increases from 4.0 m/s to 36 m/s over 4.0 s time interval. What is its average acceleration?

The race car in the previous problem slows from 36 m/s to 15 m/s over 3.0 s. What is its average acceleration?

A car travels at uniform velocity a distance of 100 m in 4 seconds. What is the velocity of the car?

If a sprinter runs 100 m in 10 seconds, what is his velocity?

Acceleration can be negative.
