Mass is number of paticles present in an object. Weight is by how much force earth is pulling us.

Mass is always same, either on moon or on earth. SI unit = kg/g Weight can vary at different places. It is the force exerted by an object on the earth/surface. SI unit = N (Newton)

Mass cannot vary, it always remain same at all places. It is measured through beam balance. It's unit is kg. Weight can vary at different places like on earth ? and moon? . It is measure through spring balance. It's unit is Newton.

There are 2 resons for which the weight at equator is less that of poles :

1. Rotation of the earth:

The general equation for gravitational acceleration at various latitudes can be given as:

r is radius of earth , is angular velocity of earth and is angle of latitude.

Now, at equator , value of =0°, but at poles = 90° , so we can say:

Since the gravitational acceleration at the equator is less than that of the poles an object will have lesser weight at the equator.

2. Spheroidal shape of earth:

The it is not completely spherical and the radius at the equator is slightly greater as compared to that of the poles.

That is why , the gravitational acceleration at the equator is slightly less as compared to that of the poles.

And hence the weight is lesser at the poles.
