How to calculate mass using gravity?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
To calculate mass using gravity, rearrange the weight formula F = mg to get: m = F/g or m = W/g
Where:
- m = mass (in kilograms)
- F or W = weight/force (in Newtons)
- g = acceleration due to gravity (9.8 m/s² on Earth)
For example, if an object weighs 98 Newtons on Earth, its mass would be 98 ÷ 9.8 = 10 kg. Remember that mass is constant regardless of location, while weight changes depending on the gravitational field strength.
