... increasing, but its RATE of increase (acceleration) is decreasing.
When the magnitude of the force dwindles to zero, the object's speed will stop increasing.
To solve the problem we must know about the concept of force and acceleration.
We know that force is a product of mass and acceleration. It is given by the formula,
F = m x a
Acceleration is defined as the rate of change of velocity. It is given by the formula,
[tex]a = \dfrac{dv}{dt}[/tex]
As it is given to us that the force is been reducing and it is in the direction of the object in which it is moving, therefore, the acceleration of the object is decreasing.
And since acceleration is the rate of change of velocity, therefore, if the acceleration of the object reduces that means there is no change in the velocity, thus, the velocity of the object is constant.
Hence, if the magnitude of the force is decreasing with time. The speed of the object is getting constant.
