Question

explain the meaning of the following statement '1 kgf =9.8 N'

Answer 1

The gravitational unit of force on S I is 1 kg wt or 1 kg f. It is that much force which produce an acceleration of 9.8 ms-2 in a body of mass 1 kg.
1 kg wt = 1 kg f = 1 kg X 9.8 ms-2 = 9.8 N

OR

It means that amount of force required to attract a body of mass one kg by earth is 9.8N

Answer 2

Explain the meaning of '1kgf = 9.8N'.

As we know that gravitational force is 9.8N

It means the force of attraction on a body of 1kg of mass is 9.8N

Therefore, 1kgf = 9.8N

It means that amount of force required to attract a body of mass 1kg by earth is 9.8N.
