Zorluk: ZorNewton's Third Law (Action/Reaction)

When a massive steel cargo ship collides with a small wooden fishing boat, the impact force exerted by the cargo ship on the wooden boat is significantly greater in magnitude than the reaction force exerted by the wooden boat on the cargo ship, due to the ship's vastly greater mass and momentum.

Cevap: Cevap

Cevap

The statement is false.
The statement is false because Newton's Third Law mandates that forces between two interacting objects are always exactly equal in magnitude and opposite in direction, irrespective of their differing masses or momentums.

Adım Adım Çözüm

1
Analyze the interacting bodies and the nature of the forces described in the scenario.
The two bodies are a massive cargo ship and a small wooden boat experiencing a collision, which constitutes an interacting force pair.
Identifying the system and the interaction is necessary to apply the correct physical laws.
2
Apply Newton's Third Law to the interaction.
The law states that force pairs between two interacting objects are always equal in magnitude and opposite in direction (Fship=−FboatF_{ship} = -F_{boat}).
This fundamental law dictates how forces operate between any two interacting bodies, regardless of their physical properties.
3
Evaluate the role of mass and momentum mentioned in the statement.
While the ship has significantly greater mass and momentum, these factors determine the resulting acceleration (a=Fma = \frac{F}{m}) and subsequent damage, not the magnitude of the interacting force pair itself.
It is critical to distinguish between the contact force itself and the effects (acceleration, deformation) of that force.
