Question

what is the first law of Einstein​

Answer 1

Answer:

1) Objects in motion (or at rest) remain in motion (or at rest) unless an external force imposes change. (2) Force is equal to the change in momentum per change of time. For a constant mass, force equals mass times acceleration. (3) For every action, there is an equal and opposite reaction

Answer 2

LAWS OF MOTION

Objects in motion (or at rest) remain in motion (or at rest) unless an external force imposes change. (2) Force is equal to the change in momentum per change of time. For a constant mass, force equals mass times acceleration. (3) For every action, there is an equal and opposite reaction
