Changing Gravity Man on the Moon
Title Page

• This is an example of a mini lesson on
  determining the effect of the moons
  gravitational pull on a persons weight.

What is Gravitational Pull?
Information Slide

• Gravitational pull is the force that causes all
  objects to be pulled towards one another. The
  gravitational pull varies from surface to surface
  depending on the size, or mass, of the object. It
  is the gravitational pull of the sun that keeps
  the planets in orbit around it.

How to Calculate Weight in Relation to Gravity
Information Slide

• The gravitational pull of the earth is 9.8 meters
  per second squared. The moon is roughly
  one-fourth the size of the earth and has a
  gravitational pull of 1.63 m/s2. To find your
  weight on the moon, all that is needed is a
  simple proportion

1.63 X 9.8 W
W your weight on earth.

What is the Weight of a 210 lb. Astronaut on the
Moon?
Question Slide
Select correct answer

• 1262.58
• 39.42
• 34.93
• .0761

5
Sorry, that was Incorrect.
Wrong Answer Slide

• Remember that the gravity of the moon is
  approximately one-sixth of the earth.
• Look back at the given proportion and try to
  calculate the astronauts weight again.

6
Correct! Youre Right!
Right Answer Slide

• An astronaut who weighs 210 lbs. on earth will
  weigh 34.93 lbs. on the moon.
