Calculate the weight (in Newtons) of a 100 kg person on Earth.
The weight of a 100 kg person on Earth is 980 N. You find this by taking the mass of 100 kg x acceleration 9.8 m/s2 = force of 980 N.
The weight of a 100 kg person on Earth is 100 N. This is because mass and weight are the same and do not change.
The weight of a 100 kg person on Earth is 10.2 N. You find this by taking the mass of 100 kg / the acceleration 9.8 m/s2 = force of 10.2 N.

The acceleration of gravity is 28 times greater on the Sun than on Earth. Imagine there is a space suit that would let a person stand on the surface of the Sun. Calculate the weight (in Newtons) of a 100 kg person on Sun.
The weight of a 100 kg person on Earth is 980 N. You find this by taking the mass of 100 kg x acceleration 9.8 m/s2 = force of 980 N. On the Sun the person would weight 28 times more so you would multiply 980 N x 28 = 27, 440 N.
The weight of a 100 kg person on Earth is 100 N. This is because mass and weight are the same and do not change. On the Sun the person would weight 28 times more so you would multiply 100 N x 28 = 2, 800 N.
The weight of a 100 kg person on Earth is 10.2 N. You find this by taking the mass of 100 kg / the acceleration 9.8 m/s2 = force of 10.2 N. On the Sun the person would weight 28 times more so you would multiply 10.2 N x 28 = 285.6 N.
