Question

It is difficult to start motion with a heavy box and also difficult to stop it once it's moving. This best exemplifies:

• A. Conservation of energy
• B. Property of inertia
• C. Action-reaction principle
• D. The concept of power

Answer 1

Answer:

B. Property of inertia

• Inertia is defined as the inherent property of a body to resist any change in its state of rest or uniform motion in a straight line.

• This concept is formally established in Newton's First Law of Motion, also known as the Law of Inertia.

• The resistance to change is directly proportional to an object's mass; therefore, a heavier box has greater mass, resulting in higher inertia.
