More Information
Inertia is an object's resistance to change in its state of motion. A heavier object has more inertia. If the force you apply is less than the force of inertia, the object will not move.
Tips
A common mistake is to think that inertia only applies when something is moving. Inertia applies to objects at rest as well.
