in freefall it has no weight , only mass

from f=m*g, if a 1 kg mass freefalls under earth gravity (9.81 m/s^2)

then f = 1 *9.81 = 9.81 newtons, sometimes g is rounded to 10, then the answer would be 1*10=10 newtons

air resistance (which is a force ( v^2 * drag coefficient)) is ignored here

What is the momentum law the states that the total momentum of an object is constant if no outside force acts on it?

Law of inertia? Newtons first law.


An object's weight in Newtons Law is equal to force of gravity that acts on that object?

In Newton's law of universal gravitation, an object's weight is equal to the force of gravity acting on it. This force depends on the mass of the object and the acceleration due to gravity, typically 9.81 m/s^2 on Earth. The weight of an object can be calculated using the formula: weight = mass x acceleration due to gravity.


Does newtons second law state that if an unbalanced force acts on an object it will move at constant velocity?

No, Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma). If there is an unbalanced force acting on an object, it will accelerate, not move at a constant velocity.


What happens when no force acts on an object?

If no force acts on an object, it will remain at rest if it was initially at rest, or continue moving at a constant velocity if it was already in motion. This is known as Newton's first law of motion, which states that an object will remain in its state of motion unless acted upon by an external force.


Newtons first law of motion states that an object remains at rest unless a force acts on it?

Yes, the law states that an object continues its state of rest or uniform motin in a straight line unless it is compelled to change that state by an external source impressed upon it.

What is the net force that acts on a 10- freely falling object?

Ten newtons downward, by definition.


What is the principle of newtons third law of motion?

Newton's Third Law states that if an object "A" acts on an object "B" with a certain force, then object "B" will act on object "A" with the same force (but in the opposite direction).


What happens when an unbalanced force acts on an objects?

as stated in newtons second law of motion- an object acted upon by an unbalanced force will accelerate in the direction of that force


What is the measure of the pull of gravity on an object called?

Newtons (N) It was first thought of by sir issac newton > The force acts equally on both objects, and is rated in newtons.


What is the momentum law the states that the total momentum of an object is constant if no outside force acts on it?

Law of inertia? Newtons first law.


What is the acceleration of the object when a Newton force acts on it what is the objects mass?

The acceleration of an object can be calculated by dividing the force (in Newtons) acting on it by the object's mass (in kilograms), using the equation: acceleration = force / mass. So, if a force of 10 N acts on an object with a mass of 2 kg, the acceleration would be 10 N / 2 kg = 5 m/s^2.


What is another name for newtons law?

the name for newton's third law is the law of inertia. it states that an object that is moving will keep in motion unless an outside force acts upon it and an object at rest will continue to be at rest until an outside force acts upon it.


What is the net force that acts on a 1-kg freely falling object?

The net force acting on a 1-kg freely falling object is equal to its weight, which is the force of gravity pulling it downward. This force is approximately 9.8 newtons (N) on Earth.


Is it true that an object in motion at a constant velocity will change its motion only if a central force acts on it?

yes it is one of newtons laws of motion
