What does it mean to sat that the net force determines an objects acceleration?

There are many forces acting on a body. But, the moves because of the net force acting on it. So, we can say that the body accelerates because of net force acting on it only.

What does forces in terms of acceleration mean?
As defined by Isaac Newton, force equals mass times acceleration.
The force of gravity acting on an object describes the objects?
What do you mean.If u mean gravitational force then gravitational force never changes in physics it is consider -9.8N the negative meaning downward and (N) meaning newtons, which is a force. Yet if you mean weight then that would be F=MA which is force equals mass x acceleration and in a free body digram that doesn't have a natural force or tension or in other words free falling then the force acting on it would be the kilograms which is represent as mass x the acceleration which would be represented as gravity. that would give you the force downward. which coincidently is your weight.
Does newtons second law explain how an unbalanced force on an object causes it to accelerate?
Newton's secong law indicates that an object accelerates in the presence of a net force on it. But it doesn't mean that an object should accelerate when two forces act on it. It depends more on the orientation or direction of force. Say if 2 forces act in opposite directions then the net force would be 0 and thus no acceleration is caused. Hence take NET FORCE, not just force acting into consideration.
Acceleleration is directly proportional to force but inversely proportional to mass what does this mean?
It means that if you increase the force, acceleration will increase. However, if you increase the mass of the object you are accelerating, the acceleration will decrease. It all stems from the basic equation F=ma, where F is the force, m is the mass and a is the acceleration. Rearranging for a gives a=F/m. This means that as m is the denominator, if it doubles and F remains constant, a will halve.
What happens to acceleration if both mass and force remian constant?
Since acceleration = force / mass, it will fall as mass increases.Progressive loss of mass is much more likely to occur in real life - for instance with a rocket, which burns fuel as it goes. In this case, acceleration will increase.
What mean acceleration?
acceleration= force/mass and also change in direction,speed are acceleration
What does forces in terms of acceleration mean?
As defined by Isaac Newton, force equals mass times acceleration.
What does F equals MxA mean?
I think you mean Newton's equation. Force = mass * acceleration
How does the gravitational force between two object's change if the mass of one of the objects is doubled?
Assuming by "the force acting on an object" you mean the cause of its acceleration, its acceleration will be doubled. If there is more than one force acting on it, the vector of the force will have to be analyzed by its effect on each of the other forces.
What is the effect gravity has on objects of unequal forces?
It isn't clear what you mean by "objects of unequal forces". Gravity exerts a force on objects.
What can force do?
Force makes objects change their direction. Though this does not mean without force all would be still as the man before me has said (There would be nothing to be still). It gives people the wrong idea of the term force. Now, one could say acceleration is change in direction. If some thing goes up because you throw it in the air then gravity (gravitational force), exclude air resistance slows the object down until it defeats the force from your hand and the object returns to earth. This is due to the force of gravity from the earth pulling the ball down to the earth and changing the objects direction or acceleration so its decreases the magnitude of acceleration and also changes it's direction towards the earth. As acceleration has magnitude and direction. So this shows that an object could move without force acting on it though the acceleration and magnitude of the force would never alter. It only seems that force makes motion because the frictional force that opposes you changes your direction to stationary. Forces can also deform objects as the impulse of the force can break bonds in solids.This is all summed up in Newton's first law of motion but I am going to say all 3 laws:Law 1: If no net force acts on a body then it can not ACCELERATE.Law 2: The net force on a body is equal to the product of the bodies mass and acceleration. I.e. F = M x ALaw 3: When two bodies interact, the forces from each other are equal in magnitude but opposite in direction.
Why there is no force of attraction between closer objects?
If you mean gravitational attraction, there is such a force between ANY two objects. The force depends on the distance (if two objects are closer, the attraction is stronger), and on the masses involved (if the masses are larger, the force is larger). The masses of "everyday" objects, for example two people, are so small (for the purposes of the gravitational force) that the force is hard to measure.
What does gravity mean in space?
"Gravity" is a force between any two objects. This specific force depends on the masses (more mass --> more force), and on the distance between the objects (more distance --> less force).
Why acceleration is maximum at extreme points of simple pendulum?
f=ma that in equilibrium postion the force are zero that why the in sample pendulum the force is zero that mean that acceleration is also zero that point velocity is maximum

How do you find N?
If by N you mean Newtons, then the formula to use would be Force=mass x acceleration. Newtons is the unit of measurement for force
