Question

If you took two marbles of different sizes, what would you expect to observe about the relative magnitudes of their terminal velocities?

Step-by-Step Solution

Answer

The terminal velocity of the larger marble is smaller than the smaller marble.

Step 1: Velocity

The pace at which an object's position changes with respect to a frame of reference and time is called velocity.

Step 2: Explanation

The terminal velocity depends on the viscosity of the fluid and the size of the object. If the marbles have the same weight but different sizes, the terminal velocities will be different.

Step 3: Conclusion

The resistance to air increases as the surface area grows larger. If both marbles are the same weight, the air resistance for the more enormous marble will be greater, resulting in a lower terminal velocity for the more oversized marble.

Thus, the more oversized marble will have a smaller terminal velocity.
