alleryNewton's first law of motion is essentially a statement of:
AConservation of momentum
BInertia of a body
CEquivalence of mass and energy
DAction–reaction symmetry
Answer & Solution
Correct answer: B. Inertia of a body
1. The first law says a body remains at rest or in uniform motion unless an external force compels it to change that state.
2. This property of a body to resist change in its state of motion is called inertia.
3. Hence the first law is, in essence, a statement of inertia.
