What would be the situation if mass were added to or lost from a system while a constant force was being applied to the system?
Since Force = Mass x Acceleration If force is held constant and one varies the mass then the acceleration will vary according to the equation: Acceleration = Force / Mass As a result, the acceleration is inversely proportional to the mass of the object. In other words, if one increases the mass of the object, the acceleration of the object will decrease proportionally. Similarly, if one decreases the mass of the object, the acceleration will increase proportionally.
How does the mass vary with acceleration of constant force?
In theory, if you keep the force constant and vary the acceleration, the mass will vary inversely to the acceleration. In other words, if the acceleration increases, the mass will decrease; if the acceleration decreases the mass will increase. This is according to Newton's 2nd Law illustrated by the equation a=F/m. This is really a mental exercise, because this particular experiment could not actually be performed in a typical physics laboratory.
How much more force is needed to give same acceleration to a 1500 kilogram car than to a 500 kilogram car?
Looking at the equation F=ma we can see that if we keep the acceleration constant the Force will vary directly to the mass. So from your problem, if we go from 500 kg to 1500 kg (3x larger) the Force will also have to be 3x larger.
Which describes an object's velocity that changes by the same amount each second?
If the acceleration is constant, yes. However, the acceleration of an object can vary. The rate of change of acceleration is called jerk.
Why is law of conservation of momentum important?
Momentum is the concept that links the action of a force and the change of speed it produces. It accounts for the fact that a force will produce a large acceleration in a small mass but a small acceleration in a large mass. If this law was not universal, then the outcomes of identical interactions would vary, contrary to the basic tenets of physics.
How does force vary with acceleration at constant mass?
If acceleration is kept constant but you vary the mass, the force will vary in direct proportion to the mass. If the mass increases, the force will also increase, and if the mass decreases the force will also decrease. Newton's 2nd Law, illustrated by the equation F=ma, illustrates this.

How does acceleration vary with force?
Newton's Second Law: force = mass x acceleration.

What is the definition of weight?
The weight of an object, in a gravitational field, is a force that is equal to the mass of the object multiplied by the acceleration due to gravity.Weight is the vertical force exerted by a mass as a result of gravity.Weight can be expressed mathematically asFw = mgwhere,Fw = force, or weight, resulting from an accelerating objectm = mass of an objectg = acceleration due to gravityThis equation is a variation of Newton's second law of motion. In the general form of the equation the variable g is replaced by the variable a which stands for any acceleration acting on an object with mass. Whenever an acceleration is caused by gravity, the force on that object is called it's weight.The weight of an object should not be confused with the mass of an object. The mass of an object is constant no matter where in the universe the object is located, but it's weight can vary in different places because the force of gravity can vary depending on location.== ==

What is the relationship between free-fall acceleration and mass?
The rate of free-fall acceleration is a constant based upon the local gravity - on planet Earth the acceleration is 9.8m/s2. Mass is a function of the object being measured or observed, which can vary considerably. The two do not directly affect each other, but both taken together determine the force of the object in free-fall - by knowing the free-fall acceleration and the mass of the object, you can calculate how hard it will impact the Earth.
What information do you need to measure acceleration?
The answer can vary depending on circumstances. The average rate of acceleration may be measured as a change in velocity over time. But it is also possible to measure acceleration using force and mass.
Why gravitational constant is constant while when acceleration due to gravity is change?
gravity of earth is constant in any plane but the acceleration may vary becoz of irregular plane
Which describes an object's velocity that changes by the same amount each second?
If the acceleration is constant, yes. However, the acceleration of an object can vary. The rate of change of acceleration is called jerk.
What is the property of matter that is not affected by gravity and is constant?
The property of matter that is not affected by gravity is mass. An object has the same mass regardless of the force of gravity, however it's weight can vary. Weight is the force of gravity acting on the mass of an object.

Momentum is the concept that links the action of a force and the change of speed it produces.
