Inertia is the tendency of an object to resist changes in its state of motion. It is a property of matter and is directly related to an object's mass. The greater the mass of an object, the greater its inertia.
Inertia does not directly affect an object's speed. However, an object with greater inertia will require more force to change its speed compared to an object with lower inertia.
Yes, inertia can be overcome by applying a force to an object. This force will cause the object to accelerate and change its state of motion.
Mass is a measure of the amount of matter in an object, while inertia is a property of matter that describes an object's resistance to changes in its state of motion. In other words, mass is a quantitative measure, while inertia is a qualitative property.
Newton's first law of motion states that an object will remain at rest or in motion with a constant velocity unless acted upon by an external force. This is directly related to inertia, as an object's inertia is what causes it to resist changes in its state of motion.
