If a person weighs 240 lb on Earth, that person's weight on the Moon would be what?  The moon's mass is about 1/81 that of earth, and diameter about 27% that of earth.

for orbital velocity, do you always add 6400 km to the altitude of orbit?

What distance, in meters, would be needed between a 451 kg object and a 1,709 kg object to produce a gravitational force of 9.94x10-8 N?

Suppose an elephant has a mass of 1,800 kg and a person has a mass of 75 kg. If the strength of gravitational force on the person was 735 N, what would be the gravitational force on the elephant? (Assume both the person and elephant are on Earth’s surface.)

If a horse weighs 148.5 on the moon how much would it weigh on earth

On Mars my sister’s dog weighs 62 N. What is its mass in kg? (Mars acceleration of gravity is 3.7 m/s2). Give your answer in kilograms with one decimal place.

Find the force of gravity between Earth and the Sun (Sun's mass = 2.0×10302.0×10^30 kg; average Earth-Sun distance = 1.5×10111.5×10^11 m).

If a person weighs 792 N on the Earth, what is the person's weight on the Moon?

A race car rounds a curve at 60 m/s. The radius of the curve is 380 m and the car's mass is  1,883 kg. What is  the centripetal force acting on the car? Calculate answer to one decimal.

Suppose a satellite (not the Moon) orbits Earth exactly every 30 days. Find its distance from Earth center in meter.
