Textbook Problem

A fish rests on the bottom of a bucket of water while the bucket is being weighed on a scale. When the fish begins to swim around, does the scale reading change? Explain your answer.

To determine

Whether the scale reading of weight changes when the fish begins to swim in the bucket.

Explanation of Solution

The propulsive force is the force which is required by an object to accelerate in the required direction.

The weight of the system depends on the mass of the system. The fish is initially at rest at the bottom of the bucket of water. As the fish begins to swim around the propulsive force is acts, the mass still remains the same of the bucket of water that contains fish...
