Question

Ps help. Many this and God Bless:)

What is the weight of a mass of 550grams

(a) on Earth,

(b) on the moon.

Answer

Answers provided by SAHmom are correct. To add on, at secondary level and below, we usually use 10 m /s^2 for gravitational acceleration on Earth. The more precise value (9.81) is used at A Levels and above.

I think question should provide info like:

g (Earth) =10m/s2     or other value like 9.8, etc

g (moon) = 1/6 of g (earth)    or     given value.     Pls check again.

Weight (N) = mass (kg) x gravitational acceleration (m/s2)

(a) Weight on Earth (N) = 0.55 (kg) x 10 (m/s2) = 5.5N

(b) Weight on moon (N) = 0.55 (kg) x 10 (m/s2) x 1/6  = 0.917N
