Which of the following formulas is the correct equation for the law of Universal gravitation?
F=d2GM1M2
F=mg
F=m1m2Gd2
F= F=d2KQ1Q2
A moon is located at 1 unit out from the planet it orbits. If that moon was orbiting at 2 units out from the planet, how much would the gravitational force on the moon be compared to its distance at 1 unit?
41 of the original force
61 of the original force
twice as much
4 times as much
A person on the Earth weighs 180 pounds. How much will they weigh on the moon? ( Note: The moons "g" is 61 times that of Earth)
30 lbs
360 lbs
0- you are weightless in space
18 lbs
If I double the mass of one object without changing anything else, What would happen to the gravitational force between that object and any other object?
Doubles
Quadruples
Cut in Half
41 as much
What happens to Gravitational force if I double both of the masses but don't change their distance?
doubles
half as big
4 times bigger
41 as much or 4 time smaller
Calculate the force of gravity (F) between two objects whose masses are m1 = 100 kg and m2 = 1000 kg if they are separared by a distance of d = 500 m.
2.67 * 10-11 N
0.4 N
6.67 * 10-11 N
1.3 * 10-8 N
Find the distance between two objects whose masses are m1 = 4,500 kg, and m2 = 8,700 kg; if the gravitational force between them is F = 2.0 x 10-8 N.
130565.25 m
361.34 m
0.19575 m
0.783 m
The reason why ocean tides happen is
Electrical forces between the sun and the moon
gravitational forces between the Earth and the moon.
Magnetic forces between the Earth and the moon
Motion of the moon around the earth
Which of the following does not apply to the moment when Spring tides happen?
during new moon
during full moon
when the moon and the earth are alligned with the sun
during quarter moon
I man who weighs 1000N on the surface of the earth will weigh how much at twice the distance in the atmosphere.
500 N
250 N
2000 N
4000N
At what point is the force of gravity on an object greatest
At the center of the earth (Core of the earth)
At twice the distance from the surface of the earth
At the surface of the earth
The force of gravity ios the same irrespective of distance from the center of the earth
If the sun's mass is 2.0x1030 kg, and itsradius is 7.0 x 108 m, what is the strength of its gravitational field, "g"?
9.8 m/s2
272.2 m/s2
27.2 m/s2
200 m/s2
why does a bungee jumper feel weightless on their way down?
Because of Lack of support force as they fall
because they are really weightless
because their mass is negligible as they fall
because they are falling at constant velocity
Is it true that the moon falls?
No, it could have fallen by now.
No, there is no good explanation as to why
Yes, the moon is falling around the earth due to its tangential velocity.
Yes, the moon is falling straight down.
