The mass would remain the same and the weight would change

Explanation:

A rock is made out of matter; matter is never destroyed or made. Mass is the composition of matter in the rock. Mass is always constant.

Weight is a force, measured in Newton. The formula for weight (force) is;
$force = mass \times acceleration$
The force in this case is the weight and the acceleration is the gravitational pull. Since the mass is constant and the gravitational pull of earth and of the moon differs, the the force changes.

Answer from: Quest

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
