e-zero said:I would say that if its lowering at a constant speed then there is no acceleration.
Also, I would say that, if anything, since its moving downwards it would be decelerating. Which I guess is the same as accelerating upwards??
No, it would just mean that the net force is zero and thus the acceleration, not the speed, is zero. The speed could be anything, as long as it remained constant.e-zero said:How could mg = Ft if it were lowered at a constant speed?? That would indicate that the bucket is at rest.
The force acting on the bucket is the weight of the bucket itself, which is equal to the force of gravity on the bucket's mass.
The length of the rope does not affect the speed of the bucket as it is being lowered. The speed is determined by the force of gravity and the weight of the bucket.
The acceleration of the bucket is directly proportional to the mass of the bucket. This means that as the mass of the bucket increases, the acceleration also increases.
The potential energy of the bucket decreases as it is being lowered, since potential energy is dependent on the height of an object and the bucket is moving closer to the ground as it is being lowered.
The bucket does not accelerate at a constant rate because the force of gravity remains constant, but the weight of the bucket decreases as it is being lowered due to the work being done by the rope. This results in a decrease in the net force on the bucket, causing a decrease in acceleration over time.
