Science fiction movies depict astronauts landing on large asteroids. The gravitational force of such bodies is typically less that 0.1 N/kg. Given an astronaut with a mass of 77.3 kilograms:

(a) What would his weight be on Earth (g = 9.8 N/kg) in newtons and pounds (force) ?

(b) What would his weight be on an asteroid (g = 0.08 N/kg) in newtons and pounds (force) ?

The weight on Earth would be:

77.3 * 9.8

= 757.54 Newtons

1 Newton = 0.2248 lbf

757.54 * 0.2248

= 170.29 lbf

On the asteroid:

77.3 * 0.08

= 6.18 Newtons

Applying the same conversion:

77.3 * 0.2240

= 17.31 lbf
