Relation between Gravity, weight and lifting.

Gravity

Every planetary body (including the Earth) is surrounded by its own gravitational field, which can be conceptualized with Newtonian physics as exerting an attractive force on all objects. Assuming a spherically symmetrical planet, the strength of this field at any given point above the surface is proportional to the planetary body's mass and inversely proportional to the square of the distance from the center of the body.

Weight

The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, 

w = mg. 

Since the weight is a force, its SI unit is the newton.

Lifting

When an object is lifted or projected upward, work must be done against the resistance from gravity. In some situations, the resistance of inertia from accelerating the object and air resistance must be taken into account.

According to Newton's third law For every action, there is an equal and opposite reaction.

" Therefore the force applied for lifting any object in the Earth should more than the force exerted due to gravitation of the earth"
