### How is it possible for an object with a large mass acted on by a large gravitational force to have the same acceleration as an object with a small mass acted on by a small gravitational force?

Because the large mass NEEDS more force on it in order to get
the same acceleration,
and the small mass NEEDS less force on it in order to get the
same acceleration.
Since the large one HAS more force on it and the small one HAS
less force on it,
the end result is that EVERY mass gets the same acceleration as
long as they're
all on the same planet.

###### Asked in Physics, Isaac Newton

### Which describes how the same force affects a small mass and a large mass?

Gravitationally, the same force does
not affect a small mass and a large mass.
The small mass is acted upon by a smaller gravitational force,
and the large mass
is acted upon by a larger gravitational force. The result is
that the small mass and
the large mass fall with the same
acceleration, and meet the ground with
the same
speed. During the fall, onlookers typically nudge each other and
remark to each other:
"My word! The large mass weighs more
than the small mass!" They are correct in their
impression, and the scientific reason behind their perspicacious
observation is the fact
that the gravitational force acting on the large mass is greater
than the gravitational
force acting on the small mass.

### Can a person's weight change and their mass remain the same?

weight is mass times acceleration.
If the acceleration is zero, e.g. weightless in space, then the
mass you have is still the same, but since there is no
acceleration, there is no weight.
Experiment. If you attach a small mass to a spring balance, then
while you are lifting it, the weight will increase.

###### Asked in Physics

### What happens to the acceleration as you increase the mass?

Newton's Second Law: Force = mass x acceleration. Solving for
acceleration: acceleration = force / mass.
Therefore, if you increase the mass, the same force will produce
less acceleration.
Newton's Second Law: Force = mass x acceleration. Solving for
acceleration: acceleration = force / mass.
Therefore, if you increase the mass, the same force will produce
less acceleration.

###### Asked in Physics, Weight and Mass

### Why is it easier to change the motion of an object with a small mass than it is to change the motion of an object with a large mass?

F=mxa, m = can be small or large, a = change the motion
(acceleration), F = the cause of the change the motion
F1 changes the motion of m1 at a
F2 changes the motion of m2 at a (same force, same size
mass)
(F1+F2) changes the motion of (m1 +m2) at a
So it takes twice the force (F1+F2) to move twice the mass (m1 +
m2) at the same change in motion (acceleration). If (F1 + F2) were
to move smaller mass (m1) the acceleration would be larger. The
"why" is hidden in the formula.

###### Asked in Science, Physics, Weight and Mass, Gravity

### If the acceleration due to gravity is the same for all objects does the mass have any effect the acceleration due to gravity?

No. If you assume no air resistance, different objects will
receive the same acceleration, regardless of their mass.
No. If you assume no air resistance, different objects will receive
the same acceleration, regardless of their mass.

No. If you assume no air resistance, different objects will receive

###### Asked in Science

### Explain why the gravitational acceleration of any object near the Earth is the same no matter what the mass of the object is?

Strictly speaking its not the same .
This equation calculates the acceleration:
acceleration = ( G * ( m1 + m2 ) ) / d2
where:
G = newtons gravity constant
m1 = earths mass (kg)
m2 = objects mass (kg)
d = distance between centres of gravity (metres)
The earths mass is so large however, only a significantly large
object mass would make a real difference to the acceleration.
