Question

(A) The weight of an object on Earth is calculated using the formula $W = m 	imes g$,where $m$ is the mass and $g$ is the acceleration due to gravity

Vedclass · Accepted Answer

Weight on Earth is $500\, N$; mass remains same,weight decreases on the Moon.

Vedclass · Answer

(A) The weight of an object on Earth is calculated using the formula $W = m 	imes g$,where $m$ is the mass and $g$ is the acceleration due to gravity $(g \approx 10\, m/s^2)$.Weight on Earth: $W = 50\, kg 	imes 10\, m/s^2 = 500\, N$.On the Moon,the mass of an object remains constant because it is an intrinsic property of the body.However,the weight on the Moon changes because the acceleration due to gravity on the Moon is approximately $1/6$th of that on the Earth. Therefore,her weight on the Moon will be $500/6 \approx 83.33\, N$.

The mass of a girl is $50\, kg$. What will be her approximate weight on the Earth? How will her mass and weight change on the surface of the Moon?
