Mass is measured on a triple beam balance units = GRAMS.

Volume is measured in two ways.

Regular Object = Length X Width X Height units = cm3

Irregular Objects units = mL

 Pour about 50 mL of water into a graduated cylinder. Measure and record the exact amount.

 Add the object. Measure and record the new water level.

 SUBTRACT the original water amount from the new water level to find the volume of the object.

= MASS (g)

VOLUME (cm3

)

Example One:

A mineral has a mass of 100g and a volume of 10 mL. What is its density?

= mass = 100g = 10 g/mL

Volume 10 mL

Example Two:

A mineral has a mass of 25 g and a volume of 5 cm3

. What is its density?

= mass = 25g = 5 g/cm3

Volume 5 cm3

**Mass ÷ Volume to find the numerical answer. Bring over BOTH units**

Explanation:

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
