The mass of an object on Earth is the same as its mass on the Moon. The weight is different.
Weight = m * g
Weight ( Moon ) = 40 kg * 1.6 m/s² = 64 N
If the mass of an object on Earth is 40 kg, its mass on the Moon is 40 kg and its weight on the Moon is 64 N.

Sokka is here to help!!
The answer is...
<h2>D. Counter-arguments lead to circular logic in your argument.</h2>
Because, I am right. :)
Hopefully, this helps you!!

I would go with the last two because they are the same please give me brainiest if i am right
<span />
Kinetic energy = 1/2 * m * V^2
K = 1/2 * 2kg * 4
The answer is 9.8 ms^-2, because there is only one force acting on the object so the acceleration will be numerically equal to the gravitational field strength.
