For test purposes you’ll
need to know:
• The concepts presented in the presentation.
• The vocabulary words in this presentation
• The math formulas in this presentation
Write in the journal section of
your binder:
• What is the difference between
MASS and WEIGHT? Give
examples.
• Can a melted block of ice
measuring
12.5 cm³ X 15.8 cm³ X 13.6 cm³
fit into a 2500 cm³ container?
EXPLAIN.
Can a melted block of ice measuring
12.5 cm³ X 15.8 cm³ X 13.6 cm³
fit into a 2500 cm³ container? EXPLAIN.
• NO
• EXPLAIN: The volume of the melted ice (water) is 2686 cm³. The container is 2500 cm³. 186cm³ will overflow.
What is matter?• Has mass
• Takes up space
• Sometimes cannot be seen
• Can be a solid, liquid, gas or plasma
• Doesn’t have to maintain its shape and or size.
The Law of Universal Gravitation
• The Gravitational Force increases as the mass of the object increases.
• The Gravitational force decreases as distance between the objects increase.
MASS vs. WEIGHT
• While mass is the amount of matter in an object, weight is the gravitational pull on the object.
Why do scientists use MASS instead of WEIGHT performing experiments?
WEIGHT changes MASS does not. MASS will not change
unless the amount of matter changes
Does weight change with location?
If you weighed 100 pounds on earth, you would weigh…
Mercury38 lb.
Moon16.5 lb.
Mars38 lb.
Jupiter236 lb.
Saturn91 lb.
Mars has ⅓ the mass of Earth. If the Phoenix Lander has a weight of 750 pounds and a mass of 330 kg on Earth, what would be its mass and weight on Mars?
How are MASS and WEIGHT measured?
•MASS is measured with a triple beam balance or double pan balance
•WEIGHT is measured with spring scale
How is the amount of space occupied by matter measured?
• VOLUME is the amount of space that an object takes up or occupies.
How can VOLUME be determined in a regular shaped object?
Length X Width X Height = VOLUME
LengthWidth
Height
• No matter the size or shape of
an object, DENSITY will ALWAYS
remain the same.
• Cannot be measured directly
• Expressed as MASS/VOLUME ³
