When a sailor jumps out of a rowing boat, the boat moves backwards. This represents:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. the Third law of motion.
This scenario illustrates Newton’s Third Law of Motion, which states:
'For every action, there is an equal and opposite reaction.'
When the sailor jumps forward out of the boat, they exert a forward force on the boat. In response, the boat experiences an equal and opposite force, causing it to move backward. This mutual interaction between the sailor and the boat perfectly demonstrates the third law in action.
Other options :
- First law of motion: Deals with inertia; objects remain at rest or in uniform motion unless acted upon.
- Second law of motion: Relates force, mass, and acceleration: ( F = ma ).
- Rectilinear motion: Refers to motion along a straight line; not specific to this interaction.
