Answer:
Because the weight depends of the gravity
Explanation:
This is because weight and mass are different, in order to better understand this problem we will apply an example with real values, which will help us to determine a person's weight.
A man has a mass of 80 [kg] on Earth when measuring his weight he realizes that it is 784.9 [N] and on the moon it is 130.8 [N]
<u>On Earth</u>
<u />
![g_{e} = 9.81[m/s^2]\\g_{m} = 1.635[m/s^2]](https://tex.z-dn.net/?f=g_%7Be%7D%20%3D%209.81%5Bm%2Fs%5E2%5D%5C%5Cg_%7Bm%7D%20%3D%201.635%5Bm%2Fs%5E2%5D)
Where:
g = gravity
<u>Weight on the moon</u>
<u />
Wm = 80 * 1.635
Wm = 130.8[N]
<u>Weight on the earth</u>
<u />
We = 80 * 9.81
We = 784.8[N]
<u />
In this way we can see that the weight depends on the gravity of where the person is located.

Answer:
From the initial height h
Explanation:
When a material or substance is drop from a height h, it possesses potential energy, immediately it is dropped from that height, the potential energy is gradually converted to kinetic energy, it gets to a point where the potential energy equals the kinetic energy, as the material touches the ground, all potential energy has been converted to kinetic energy already
