Question

an object which is projected vertically upwards falls again forwards the surface. why? distinguish between G and g ​

Answer 1

Answer:

An object which is projected vertically upwards fall again forward the surface due to gravitational force exerted by the earth.

Difference between G and g

________________

G

G is universal gravitational constant.

The value of G is constant for anywhere in universe.

The value of G is 6.67×10^-11 Nm^2/kg^2.

It is scalar quantity.

It's SI unit is Nm^2/kg^2

g

g is acceleration due to gravity.

The value of acceleration due to gravity ,g, is not constant at all the places on the surface of the earth.

It's Si unit is m/s^2.

It is vector quantity.

On earth the value of g is 9.8 m/s.

Since the radius of the earth at the pole is minimum , the value of g is maximum at the poles.The radius of the earth is maximum at the equator, so the value of g is minimum at the equator.
