Question

Choose the word that BEST completes the following sentence: A person on Earth would weigh a lot more on the Sun due to increased ________________.

Answer 1

Answer:

Gravitational Acceleration

Explanation:

the sun is 864,400 miles across, this is about 109 times the diameter of the earth. the sun weigh 27.96 times as much as Earth

For example, a person of 50kg on earth, weigh  1354 on the sun

this calculation is done using W= m*g

where W = mass of the person = 50

g= 9.8 m/s2 (a constant acceleration for earth)

g= 274.13 m/s2 (a constant acceleration for sun)

the sun gravitational acceleration is 30 times more than that of the earth

W = 50 * 274.13 = 13,705 N = weight of the 50kg person on sun

W = 50 * 9.8 = 490 N =weight of the 50kg person on earth

therefore, a person on Earth would weigh a lot more on the Sun due to increased in acceleration due to gravity

Answer 2

Answer: gravity

Explanation: The weight of an object is calculated by taking the product of the mass and acceleration due to gravity of the object or body at that point. That is:

W = m * g

W = weight of body or object

m = mass of body or object

g = acceleration due to gravity

The mass of a body or person is constant at any point or position.

'g' on the earth surface is 9.8m/s²

'g' on the Sun is 274m/s²

For Instance, A body of mass 2kg will weigh :

W=m*g

2 * 9.8 = 19.6N on the earth surface

2*274 = 568N on the Sun.

Therefore a body will weigh more on the Sun than on earth because the gravitational acceleration on the Sun is greater than on the earth surface.
