Mass is how much stuff there is in an object.
The more mass, the more inertia - inertia is just a fancy name for how much energy it takes to get the thing moving, or to slow it down once it is moving.
On earth, we usually use the term "weight" when we actually mean mass. But the weight of an object can change depending on the gravity field it happens to be in.
But the mass (and therefore the inertia) of the item never changes, so even if a rock weighs 1/6 on the moon it still takes the same "heft" to throw it.
Now consider 2 basketballs - one a normal one filled just with air, and another exactly the same size but filled with sand.
The one filled with sand has more mass crammed into the ball, so it has more inertia (try kicking a basketball, then try kicking one filled with sand you'll feel the difference).

The unit measure of inertia is momentum. The letter used to stand for momentum is p. To find p the formula is:
p = mv where p is momentum, m is the mass of the object that's moving, and v is the velocity of that object.
Inertia is a body's resistance to change in velocity. The more mass an object has the more inertia it has (also the more momentum).

Because inertia is calculated by multiplying mass and velocity of an object. Inertia is proportional to mass, and coincidentally proportional to velocity. Which mean inertia goes up when mass and/or velocity increase.

Inertia is the resistance of an merchandise to regulate its state of action. yet some products have more desirable tendency to face up to transformations than others this tendency of resistance transformations with mass. subsequently more desirable inertia an merchandise has, the more desirable mass it has and vice-a-versa. with the intention to assert that mass is a level of inertia. ie.MASS is without delay proportional to INERTIA.

Inertia is energy. Kenetic energy is energy stored. So,
1/2 mass x Velocity squared = kinetic energy.
Get the picture?

the heavier the object is, the more inertia it has
For example, to move 10 pounds of iron requires more force than to move 1 pound of iron
