mass of object *force of gravity
Yes, very alike, but mass is the amount of matter in an object, and weight is the force of gravity pulling down on an object.
The mass of an apple is described in grams, the weight of the same apple is described in Newtons. This is the force that a mass exerts due to the local attraction of gravity. A gram mass is consistent throughout the universe, a gram force changes, Unfortunately the weight of an apple is often expressed as a gram without noting that this is gram force.
weight
Force equals mass times acceleration, if you are sitting at rest you are not accelerating, so your acceleration is zero. The force is your mass times zero, 75 kg x 0 ms-2= 0 newtons. If the force is zero, this means the force of gravity pulling you down is cancelled out by the force of the chair pushing you up. So the forces are balanced.

No, gram is a unit of mass; the unit of force is newton.

No, it is a unit of mass.
That force is known as gravity.
When a tractor is pulling a sled there is the mass and gravity of both the tractor and sled slowing it down. There is also tension in the rope pulling the sled. whenever physics is involved to solve a force there is usually a frictional force acting on the objects. The formula to use is F=ma. The total mass is the mass of the objects put together and the total force is the force that the tractor is pulling at minus mg (mass x gravity) and minus the frictional force. The tension (T) is calculated using the formula T=W+ma (W=mgh), using only the mass of the sled.
Mass helps the gravitational force by pulling the object down

Weight is a result of the Earth pulling us down. The force we are pulled down is dependent on Earth's mass, so on another planet (with a different mass) one would be pulled down in a different manner.
