    Which object has more inertia and why? A moving car or a stationary ship
Asked by narenmahadevan2004 | 30 May, 2021, 09:25: PM
answered-by-expert Expert Answer
Inertia is the property that relates change of state of motion. Inertia is directly proportional to mass.
 
Mass of ship is greater than mass of car. Hence Stationary ship has more inertia.
 
Inertia of stationary ship is considered by the force required to start the motion .
 
Inertia of moving car is considered by the force required to stop the motion.
 
We know that by applying break, car can be stopped by resistive force.
 
But huge amount of force is required to start the ship.
