area time
According to Kepler's law an imaginary line from the sun to a planet sweeps out equal ___ in equal amounts of ____
planets move faster when they are closer to the sun and slower when they are farther away
According to Kepler's law which of the following statements is true
halve the distance from the sun

Reducing the distance between the masses by half
What event will produce the greatest increase in the gravitational force between two masses
attractive product of masses distance between masses
gravitational force between two masses spheres is always ____ and depends on ___ and ____
increase
if earth began to shrink but its mass remained the same the value of g on earth would _______
increase
if the mass of earth increased with no change in the radius your weight would
decrease moving faster
if the mass of the sun were doubled the period of the planets orbits would
increase
if the radius of earth decreases but mass stays the same your weight would
increase
if the radius of the planets orbits were doubled its period would
1/4 of the what it is on earth
if you stood atop a ladder on earth that was as tall as Earths radius your weight atop the ladder would be
inverse squared relationship
newton reasoned that the gravitational attraction between earth and the moon and the distance between them must has a

suppose the gravitational force between two massive spheres is 75 if distance is doubled the masses is now
closer
