What is the SI unit for gravity on Earth?

Answer 1

The standard units for most of scientific work are the SI units. A newton can be seen to be the force required to accelerate 1 kg of mass at 1 m/s2. To accelerate a 1 kg mass at 9.8 m/s2 would require 9.8 newtons, so on Earth the weight of 1 kg is 9.8 newtons.

Answer 2

is that what you were looking for

Answer 3

So for example, I have a ball that weighs 0.05 kg and to find the gravity on Earth, I multiply it by 9.8 m/s^2. I get 0.49. Would it be 0.49 N or m/s^2?

Answer 4

It would be 0.49N because you just found the force of the ball, not the acceleration of the gravity of the Earth. However, before you multiply it by 0.49, you need to make the conversion factors the same.

Answer 5

What do you mean by making the conversion factors the same?

Answer 6

It's basically 0.49 N. When you use the formula F=MA, Force is measured by Newtons. Mass is kg, and A is m/s^2. So you would get the equation F = (0.05kg)(9.8m/s^2), which you said was 0.49 N. :)
