Question

An object weighs 1247 N on Earth's surface. The acceleration due to gravity on the moon is 1.62 m/s2. What is the object's weight on the moon?

200 N


206 N


177 N


189 n

Answer 1

The answer will be 206 N

reasoning:


you must recognize that the problem gave you the force due to weight on earth, which similarly on the moon will be F = mg, just a restatement of Newton’s Second Law.

so given the 1247 N on earth:

1247 = mg
1247 = m(9.8 m/s^2)

1247
—— = 127 kg for the mass
9.8

Now implement this equation with the known mass for moon’s gravity

F = (127kg)(1.62m/s^2)

F = 205.74 N or 206 N

Hope this helped!! Thank you for posting your question.
