2. DECREASES, due to the larger distance from the source of gravity
Mt. Everest
Where is your source of gravity?
The
Center
Of Earth
weaker
NO!
Your mass hasn’t changed!
Farther
Medfield
Mt Everest
NOTHING!
Stays the Same!
Has my inertia changed? WHY?
What happens to my weight? WHY?
What happens to my mass? WHY?
Are you closer or farther from the center of gravity than in Medfield?
Is the pull of gravity STRONGER or weaker than in Medfield?

7. What are the two factors that influence an objects weight?
MASS, because the amount of matter does not change according to location.
Mass of item & strength of gravitational pull
Between mass and weight which remains constant (if no matter is added or taken)?
