Question

Physical independence of force is a consequence of 'X'. Identify 'X'.

• A. Newton's third law of motion
• B. Newton's second law of motion
• C. Newton's first law of motion
• D. All of the above

Answer 1

Answer: (C)

Newton's first law of motion

Physical independence of force is a con-sequence of 'X'.

X is Newton's first law of motion Newton's first law of motion - sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force
