Question

Which object has more inertia and why? A moving car or a stationary ship?

• A. The car, because it is moving with some velocity.
• B. The ship, because it has a greater volume than the car.
• C. The ship, because it has more mass.
• D. The ship, because it is not moving.

Answer 1

The correct option is C The ship, because it has more mass.

Inertia is the natural tendency of an object to resist a change in its state of motion or of rest.
Inertia and mass are interrelated. Heavier objects offer larger inertia.
Since the ship is much heavier than the car, ship offers more inertia.
