Answer 2

The force that acts on this mass is called weight.

Explanation:

• Weight is a measure of the force of gravity pulling down or acting on an object.

• It depends on the object's mass and the acceleration due to gravity. The acceleration due to gravity for earth is $9.8m/s^{2}$.

• The gravitational force with which a body is pulled by earth towards its centre is called weight of the body.

• Weight measures how heavy a body is.

• Depending on gravitational acceleration, weight of the same body will change. A body will weight different on earth and moon or any other planet because gravitational acceleration value for all the planets are different.
• SI unit for weight is same as Force i.e. Newton (N).
• Expression for weight is: Mass times gravitational acceleration

$Weight=mass*gravitational acceleration$

$W=mg$
