Acceleration is directly proportional to the net force. Net force is equal to the mass times acceleration, taking this into consideration we can clearly see that acceleration is inversely proportional to mass.

When the force on the object is constant, the object's acceleration is

inversely proportional to its mass.

Notice that when it comes to gravitation, the force isn't constant ...

it's proportional to the object's mass.

Put these two factoids together, and out falls the staggering implication

that under the influence of gravitation, the object's acceleration is constant,

regardless of what its mass may be. Light objects and heavy objects fall with

the same acceleration. Is that cool or what !

The acceleration of an object depends on the mass of the mass of the object and the amount of force applied is also called?

Newton's second law, which states that the acceleration of a body is directly proportional to the net force and inversely proportional to its mass, a = F/m.


How are Force Acceleration and Mass related?

(Force on an object) = (the object's mass) times (its acceleration)


One way to increase acceleration is by?

Increase the force on the object. The force must be in the same direction as the acceleration.


What happens to the acceleration of an objects when the mass is cut in half?

The acceleration of an object is proportional to the net force acting on it. So if the force is reduced by half, the acceleration will also be halved. Of course, it will still be accelerating in the same direction as before, but not as quickly.


When force is proportional to mass and acceleration why do you say force is proportional to mass multiplied by acceleration why not mass plus acceleration and so on?

By definition, if two things are proportional to one and other, they are connected by a multiplying constant. If F = m + a you would simple say F is a bigger than m and it would also require that force, mass and acceleration all shared the same dimensions and units. Clearly mass is a scalar and force and acceleration are vectors, so that is not the case. Also, if they shared the same dimensions, they would effectively be the same thing so F = m + a would be the same as F(total) = F(1) + F(2) which wouldn't tell us very much about the laws of physics at all. Also, you don't say force is proportional to mass times acceleration (it's EQUAL to mass times acceleration). It's either force is proportional to mass (in which case acceleration is the factor of proportionality) or force is proportional to acceleration (in which case it is mass).

Is the amount of acceleration directly proportional to the fore and to the mass?

No, an object's acceleration is inversely proportional to an objects mass.


How force affects mass and acceleration?

force is directly proportional to acceleration and acceleration is inversely proportional to mass of the body


Are force and mass directly proportional or inversely proportional?

Force is directly proportional to mass provided the acceleration is constant.


When acceleration is held constant and objects of different mass are observed are mass and force directly proportional or inversely proportional?

directly proportional because force=(mass)(acceleration) (f=ma)


The amount of acceleration is directly proportional to the force and inversely proportional to the mass?

Yes, that is correct.


Is acceleration directly proportional to force or it is inversely proportional to force?

Neither. It's the other way round, in both cases. Newton's Law:F = ma Solving for acceleration: a = F/m


What does newtons 2nd law state?

Newtons 2nd law means that when force is applied on any object an acceleration is produced in the direction of force which is applied on it. The acceleration produced in the object is directly proportional to the force applied on the object i.e. if force increases then acceleration will also increase and the acceleration is inversely proportional to the mass of object i.e. if the mass of the body decreases then acceleration will increase. If force is represented by 'F', acceleration by 'a' and mass by 'm' then a is directly proportional to F a is inversely proportional to m


Is accelaration directly proportional to force?

yes; the force F is directly proportional to the acceleration a and mass m; F = ma and a = F/m; the higher the force the higher the acceleration for a given mass


Is acceleration directly proportional to mass or is it inversly proportional to mass?

Depends what u mean by that. If it is free falling it would obviously be accelerating at 9.8m/s^2. If there is an incline then it depends. I believe acceleration is directly proportional to velocity though.


Describe the relationship between force and acceleration?

Force= mass x acceleration. Therefore: Force is directly proportional to acceleration.


Is force dependent on mass?

Yes, force is directly proportional to mass. Remember that Force = Mass X Acceleration.


Give an example of direct proportion?

The Circumference of a circle is directly proportional to the diameter. The constant of proportion is 'pi = 3.141592....'. Another one is force is directly proportional to mass. The constyant of proportion is acceleration.
