Question

Mass of an object is 10 kg. What is its weight on the earth ?

Answer 1

All the objects on Earth, experience an acceleration of 9.8 m/s^2 on them due to Gravity. Since, weight is also a force, the formula to calculate Weight is same as that of calculating any force. Therefore, Weight = 10 kg * 9.8 m/s^2. Weight = 98 kg.m/s^2

Answer 2

weight =mg

where m is mass of object and g is acc. due to gravity

therefore weight(W)=10 kg×9.8m/s^2

W=98N
