Question

the unit of g is ms-2 it can also expressed as


​

Answer 1

Answer:

g is the acceleration due to gravity.

It's value is 9.81 m/s^2. So the unit is m/s^2 here and it is in SI unit.

But you express it in CGS also where the value will be 981 cm/s^2. So here the unit is cm/s^2.

So, the unit of g can also expressed as cm/s^2.

Answer 2

The unit of ‘g’ is m s-2. It can be also expressed as Nkg-1

• "g" is the gravitational constant.

• The force of gravitational attraction on a mass of 1 kg on the Earth is 9.8 N.

• In SI units its value is approximately 6.674×10−11 m3⋅kg−1⋅s−2.

• we know that the force is given by,

• F = mg

• where, F is in terms of newton

• m is in terms of kg

• N = kg ("g")

• ∴ The unit of "g" is given as = Nkg-1
