What is the weight of a glider with a mass of 5.7 grams Hint: watch your units?

Weight = mass x gravity. (Where mass is in kg and gravity is in N/kg)

So, we convert 5.3 grams into kilograms.

5.3g = 0.0053 kg (Since 1kg equals 1000g)

On Earth, gravity is 10 N/kg.

Weight = mass x gravity

Weight = 0.0053kg x 10 N/kg

Weight = 0.053 Newtons (On Earth)
