Question
Newton’s first law of motion was based on which of the following statements?
- The state of rest and the state of uniform linear motion are equivalent.
- An external force is required to keep a body in motion.
- Both a and b
- None of the above
Hint:
Newton's first law of motion states that a body remains in the state of rest or uniform motion in a straight line unless and until an external force acts on it
The correct answer is: The state of rest and the state of uniform linear motion are equivalent.
The state of rest and the state of uniform linear motion are equivalent.
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
