Difference between move marble ball by straw on cardboard and move paper ball by straw on card board?

The main difference between moving a marble ball and a paper ball using a straw on cardboard is the weight and size of the objects being moved.

1. Marble ball:
- The marble ball is heavier and denser compared to a paper ball, making it more difficult to control and maneuver using a straw.
- The smooth surface of the marble ball may cause it to roll more easily and quickly on the cardboard surface.
- The marble ball may require more force and precision to move in a specific direction compared to a paper ball.

2. Paper ball:
- The paper ball is lighter and less dense compared to a marble ball, making it easier to control and maneuver using a straw.
- The paper ball may not roll as easily on the cardboard surface due to its lighter weight and less smooth surface.
- The paper ball may be easier to push and guide in a specific direction compared to a marble ball.

Overall, moving a marble ball with a straw on cardboard may require more strength and precision compared to moving a paper ball, which may be lighter and easier to control.

Move Marble Ball by Straw on Cardboard

- Requires more force: Marble balls have a higher mass than paper balls, so it takes more force to move them with a straw.
- Higher friction: The smooth surface of the marble ball creates more friction with the cardboard than the rough surface of the paper ball.
- Less control: The spherical shape of the marble ball makes it difficult to control its direction and speed.
- Can damage the cardboard: The hard surface of the marble ball can scratch or puncture the cardboard if too much force is applied.

Move Paper Ball by Straw on Cardboard

- Requires less force: Paper balls have a lower mass than marble balls, so it takes less force to move them with a straw.
- Lower friction: The rough surface of the paper ball reduces friction with the cardboard, making it easier to move.
- More control: The irregular shape of the paper ball allows for more control over its direction and speed.
- Less likely to damage the cardboard: The soft surface of the paper ball is unlikely to damage the cardboard, even with excessive force.
