The force of gravity acts on _____ objects in the universe.
All
What does the force of gravity depend on?
masses of the objects and distance between them
Equation for Universal Gravitation
Fg=Gxm1m2/r2
m1 and m2 (Def)
Masses of objects
G=?
Gravitational constant and is equal to 6.67x10^-11
r=?
is the distance between 2 objects- measured to center to center(radius)
Easier equation
W=mg
Weight = mass x gravity
Gravity =?
9.8 m/s^2
Air Pressure
is when gravity pulls on the atmosphere in turn the atmosphere pulls down on the surface of the earth
Terminal Speed
is the highest speed a falling object can reach before air resistance is equal to gravity
