Moving an object with constant force(N) in x direction

In summary, acceleration and constant velocity cannot coexist, as acceleration is defined as the instantaneous rate of change of velocity. So, it is not possible to continuously push an object with a force of 1N in the x direction and keep it at constant velocity. An example of this would be pushing a book across a table with a constant force, but the book will eventually reach a constant velocity due to the force of friction.

Is it possible to continuously push on an object with a force of 1N in the x direction and keep moving it constant velocity? What is an example?


I know that if the object was 1kg and you pushed it with a force of 1N it would accelerate at 1 m/s^2. Can you have constant velocity and constant acceleration?

No.

You can do one or the other, not both. See, acceleration is defined as the instantaneous rate of change of velocity with respect to time. However, if velocity is constant, its value at any point in time will be the same, so its rate of change will be zero, hence 0 acceleration. The converse is true as well. If you have some acceleration, then you must have a change in velocity.

It depends what the other forces are.

Can you think of an example? :smile:
 

1. How does the force applied affect the acceleration of the object?

The force applied has a direct relationship with the acceleration of the object. According to Newton's Second Law of Motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This means that the greater the force applied, the greater the acceleration of the object, and vice versa.

2. Does the mass of the object have any impact on its movement with constant force?

Yes, the mass of the object does have an impact on its movement with constant force. As stated in Newton's Second Law of Motion, the mass of an object affects its acceleration. A more massive object will require a greater force to achieve the same acceleration as a less massive object.

3. Is there a limit to the force that can be applied to an object to achieve constant movement?

Yes, there is a limit to the force that can be applied to an object to achieve constant movement. This limit is known as the maximum static frictional force. Once the applied force reaches this limit, the object will begin to move with a constant velocity instead of accelerating.

4. How does the direction of the force affect the movement of the object?

The direction of the force does not affect the movement of the object in the x direction. As long as the force is being applied in the same direction as the movement, the object will continue to move in a constant motion. However, if the force is applied in a perpendicular direction, it will cause the object to change its direction of movement.

5. Can the constant force be applied for an unlimited amount of time without affecting the object's movement?

No, the constant force cannot be applied for an unlimited amount of time without affecting the object's movement. This is because of factors such as air resistance and friction, which will eventually slow down the object's movement. Additionally, if the object is being pushed against a surface, the force will eventually overcome the maximum static frictional force, causing the object to accelerate or change its direction of movement.
