Day 132-16-11

• Topic Universal Gravitation
• Objective I can describe the relationship
  between gravitational force, mass, and distance.
• Starter Calculate the time for a ball to reach
  its pinnacle and the height it will reach on the
  planet Hickman where g -125m/s/s Vi
  35m/s.
• Where is g greater than earths g?

2
Reference
When just ONE mass is DOUBLED the Fg isINCREASED
by 2 TIMES (2X)
When BOTH masses are DOUBLED the Fg isINCREASED
by 4 TIMES (4X))

• Newtons law of universal gravitation gives the
  relationship between gravitational force, mass,
  and distance. The gravitational constant (G) is
  the same everywhere in the universe (6.67 10-11
  Nm2/kg2).

4
Radius (r)Radius represents the distance between
the two bodies of interest. (The distance is a
radius because one of the masses (m1) is orbiting
the other mass in a circle)
