It's not just about the weight:
* Energy Transfer: The key factor is the *energy* transferred to the medium (like water) by the impact. A heavier stone *can* transfer more energy, but only if it's moving at a similar speed as a lighter stone.
* Momentum: Momentum is another important factor. Momentum is the product of mass and velocity. A heavier stone has more momentum, even if moving slower. This momentum is transferred to the water, creating larger waves.
Simplified Example:
Imagine throwing a pebble and a bowling ball into a still pond.
* Pebble: It might create small ripples.
* Bowling Ball: It creates a much larger splash with bigger waves, even if you throw it slowly.
Why Amplitude Increases:
* Energy and Amplitude: The amplitude of a wave (its height) is directly related to the energy it carries. More energy transferred to the water means larger waves.
* Momentum and Displacement: The momentum of the stone also contributes to the displacement of the water. More momentum means more water is moved, leading to bigger waves.
In Summary:
While a heavier stone *can* produce higher amplitude waves, it's not guaranteed. The actual amplitude depends on:
* The speed of the stone: A heavier stone moving slowly might create waves similar to a lighter stone moving faster.
* The energy transferred: More energy transferred results in larger waves.
* The momentum of the stone: Higher momentum contributes to larger waves.
