Such an object would be accelerated, according to Newton's Second Law, at the rate of F / m (force / mass). For example, if the mass is 1 kilogram, the acceleration would be 1 meter per second square (speed would increase 1 meter/second every second); if the mass is 1/1000 of a kilogram, the acceleration would be 1000 meters/second squared, etc. In theory, such an object can get faster and faster, until it is close to the speed of light. In practice, it might be difficult to maintain such as force, however.
What else can I help you with?
How meany pounds of force to get light speed?
To accelerate an object with mass to the speed of light, you would need an infinite amount of force, as the closer an object gets to the speed of light, the more energy it would need to accelerate further due to the laws of relativity. Additionally, as of our current understanding of physics, it is impossible for an object with mass to reach the speed of light.
Which of these would change the direction of an object but not affect the object's speed?
Changing an object's direction without affecting speed requires a force that acts perpendicular to the object's velocity, such as centripetal force or gravitational force. This force causes the object to change direction while continuing at a constant speed. Other forces acting parallel to the object's velocity can change its speed as well as its direction.
What happens to a falling object when the force of gravity equals to the force of air resistance?

Is it possible for a nonzero net force to act on an object without the object's speed changing?
Yes, it is possible for a nonzero net force to act on an object without changing its speed. This can happen if the force is acting perpendicular to the direction of motion, resulting in a change in direction but not speed (as in circular motion).
How fast is an object going if its speed and time graph is horizontal?
An object can only gain speed if there is a net force on it. If a net horizontal force acting on an object is large enough, or acts for a long enough time, the object can aquire a speed up to just under the speed of light, 3 x 10^8 m/s.
What is the Formula for Force required to accelerate an object to a predetermined speed?
There is no specific force required to accelerate an object to a predetermined speed. A smaller force will produce a smaller acceleration, so it will take longer to reach the desired speed. A larger force will produce a larger acceleration, so the desired speed will be reached sooner. But either the large or the small force, or any other force, will produce an acceleration, and cause the object to reach the specified speed sooner or later.
What is the term for the highest attainable speed an object can reach as it falls?
Terminal velocity is the term for the highest attainable speed an object can reach as it falls through a fluid, such as air or water. At terminal velocity, the force of gravity pulling the object down is equal to the drag force acting against it.
How does drag work?
Drag force, or the force of air friction for a falling body, increases with speed. A falling object will reach a speed at which the force of air friction will be equal to and opposite the force of gravity. At that point, the object will no longer accelerate. It's speed will remain constant, and we call that speed (and direction) its terminal velocity.
When a object falls what does it reach because of air resistance?
When an object falls, it reaches terminal velocity due to air resistance. Terminal velocity is the constant speed an object will reach when the force of gravity pulling it down is equal to the force of air resistance pushing against it. At terminal velocity, the object stops accelerating and falls at a constant speed.
When the only force acting on a falling object is air resistance?
The word "falling" implies there is a gravitational force also. As the object gains speed, the air resistance ("drag") increases, until it equals the gravitational force. After that there is no net (resultant) force, so the object goes at constant speed.
What happensto the speed of an object if a unbalanced force acts on it?
Then the speed will change.Then the speed will change.Then the speed will change.Then the speed will change.
What is the speed of an object if nothing affects it?
If nothing affects it, then there is no force acting on it. if there is no force, there is balanced force (trivial meaning of 'nothing'). If there is balanced force, there is constant speed.This constant speed can also be maintained with a force, but the question at hand states nothing is affecting it, so that discussion is elsewhere.
When a force causes the speed of an object of decrease?
When a force causes the speed of an object to decrease, the object is experiencing deceleration. This means that the force is acting in the opposite direction to the object's motion, causing it to slow down. The magnitude of the force determines how quickly the object's speed decreases.
When falling object gains speed the air drag on it?
increases. The air resistance acting on the object grows stronger as its speed increases. This drag force will eventually balance out the force of gravity, causing the object to reach a terminal velocity where the two forces are equal and there is no further acceleration.
What causes an object to reach its terminal velocity?
An object reaches its terminal velocity when the force of air resistance equals the force of gravity pulling it down. This balance of forces causes the object to stop accelerating and fall at a constant speed.
What is needed to change the speed of an object?
To change the speed of an object, you need to apply a force to it. The magnitude of the force and the direction in which it is applied will determine how the speed changes. If the force is in the same direction as the motion, the object will accelerate; if the force opposes the motion, the object will decelerate.
Is terminal velocity depends on mass of object?
No, terminal velocity does not depend on the mass of the object. Terminal velocity is the maximum speed an object can reach when the force of gravity is balanced by the force of drag. This means that all objects, regardless of their mass, will eventually reach the same terminal velocity in a given medium.
