If you were on another planet, you would weigh
differently than on the planet Earth.
3
Weight the gravitational force exerted by the
given amount of substance.
4
The weight that you feel depends on your actual
mass.
5
The weight that you feel depends on your actual
mass. Mass the amount of substance, the amount
of material.

WEIGHT ON A PLANET
Weight on a planet depends on the amount of
matter (mass) an object has, the mass of the
planet,
9
WEIGHT ON A PLANET
Weight on a planet depends on the amount of
matter (mass) an object has, the mass of the
planet, and how far away the object is from the
center of that planet.
10
All of the planets on our solar system have
gravity.
11
Earths gravity is the force that pulls things
down toward the center of the Earth. All of the
planets on our solar system have gravity.
12
This horizontal bar graph provides a visual
representation of the gravitational pull levels
on the planets.
13
Why does the gravitational pull vary?
14
Which planets have a greater gravitational pull
than Earth?
15
Which planets have a greater gravitational pull
than Earth?
16
Which planet has the greatest gravitational pull?
17
Which planet has the greatest gravitational pull?
Jupiter
18
Jupiters gravitational pull is little more than
2.5 (2 1/2) times more than planet Earth
19
Jupiters gravitational pull is little more than
2.5 (2 1/2) times more than planet Earth

21
Gravitational pull is a significant factor on
determining weight of an object.
How would you calculate your weight on Jupiter?
22
____ my weight
How would you calculate your weight on Jupiter?
23
____ my weight Plus ____ my weight
How would you calculate your weight on Jupiter?
24
____ my weight Plus ____ my weight Plus
1/2 of my weight
How would you calculate your weight on Jupiter?
25
____ my weight Plus ____ my weight Plus
1/2 of my weight Equals my weight at planet
Jupiter
How would you calculate your weight on Jupiter?
26
My weight times 2.5 Equals my weight at planet
Jupiter
Another method to calculate weight on Jupiter, is
to use a formula.
27
2.5 times my weight equals my weight at planet
Jupiter
Calculate weight at Jupiter.
28
2.5 times my weight equals my weight at planet
Jupiter w my weight j Jupiters weight
Calculate weight at Jupiter.
29
2.5 times my weight equals my weight at planet
Jupiter w my weight j Jupiters weight
w x 2.5 j
Calculate weight at Jupiter.
30
Create a graph so others can have an idea of how
much they will weight at Jupiter.

Weight on Jupiter
x-axis
The x-axis begins with 90 pounds because an
average adult weights about this much or more.
32
Weight on Jupiter
y-axis
The y-axis begins with 200 pounds because 90 x
2.5 will equal 225.
