Let say we have a sliding box. The box is sliding because of an constant force perpendicular to the box. There is no friction and no air restistance. Does the speed of the box increase or is it constant. ?
I assume the box is on a horizontal, frictionless surface, and that the force "perpendicular to" the box acts horizontally?gunnar said:Let say we have a sliding box.

It isn't correct to say that it depends on the shape of the box. It will always accelerate, unless the plane is horizontal. It will not move to 'any' direction, either.dextercioby said:Depends on the shape of the box.On normal basis,if the force doesn't push the box to the ground and the the box be motionless before the application of the force,it could accelerate on any direction.
On the contrary, what Dextercioby said was completely correct (although possibly slightly confusing to the original questioner). Nothing was said about the force going through the center of gravity. Depending on the shape of the box, some or all of the force might simply cause the box to rotate around its center. Since nothing was said about the direction of the force, it could also move in "any" direction.ramollari said:It isn't correct to say that it depends on the shape of the box.

The difference between constant speed and increasing speed in the sliding box experiment is the rate at which the box moves. In constant speed, the box moves at a consistent rate without any changes. In increasing speed, the box accelerates and moves at a faster rate over time.
To determine if the sliding box is moving at a constant speed or increasing speed, you can use a stopwatch or a timer to measure the time it takes for the box to move a certain distance. If the time remains the same for each trial, the box is moving at a constant speed. If the time decreases with each trial, the box is moving at an increasing speed.
The speed of the sliding box can be affected by various factors such as the surface it is sliding on, the angle of the surface, the mass of the box, and the force applied to the box. Other factors like air resistance and friction can also impact the speed of the box.
According to Newton's Second Law of Motion, the acceleration of an object is directly proportional to the force applied to it. This means that the greater the force applied to the sliding box, the faster it will accelerate and the faster it will move. Therefore, the speed of the box is directly related to the force applied to it.
No, the sliding box will not reach a constant speed if the force applied is constantly increasing. As the force increases, the acceleration of the box will also increase, causing the box to continue to move at an increasing speed. In order for the box to reach a constant speed, the force applied must remain constant.
