Question

Nisha is moving to a new apartment, so she is packing up cardboard boxes and sliding the full boxes across the floor. Use Newton's first and second laws to explain why she finds that the heavy boxes are harder to get moving than the lighter boxes. square

Answer 1

Heavy boxes are harder to get moving because they have greater inertia (Newton’s first law) and require more force to achieve the same acceleration as lighter boxes (Newton’s second law).

Answer 2

1. State Newton's First Law Objects at rest stay at rest unless acted on by a net force; heavier boxes have more inertia.2. Apply Newton's Second Law

; for the same applied force, heavier boxes (greater mass) accelerate less, requiring more force to start moving.
