The bowling ball is harder to stop because it has a greater mass, and therefore a greater momentum. But the answer is that the bowling ball has a greater mass.
It is an example of momentum (sometimes called "inertia"). Velocity x mass. The bowling ball is much, much heavier. With both rolling at the same speed, the bowling ball is harder to stop because it has much more mass.
Measure it.
Usually to measure mass, one uses grams or kilograms.

The tool used would be a scale or balance. You might have to use a box to keep it from rolling off the scale surface. Measure the mass of the box, then the mass of the combination then subtract the box's mass. Common unit is pounds in the United States (that's how they are designated), and I'd guess kilograms in other countries.
A feather would have more mass than a bowling ball only if you accumulate enough feathers to equal the mass of the bowling ball. Since a single feather is much lighter than a bowling ball, it would take a very large number of feathers—potentially thousands or even millions, depending on the feather's size and type—to surpass the mass of the bowling ball. In practical terms, individual feathers are never more massive than a bowling ball.
The answer will depend on what characteristic of the ball is being measured: its radius, volume, mass, weight, shine?

Kinetic energy is a function of mass and velocity. Therefore, an object with more mass, such as a bowling ball, would have to go slower than an object with less mass, such as a golf ball. So, if given the same amount of kinetic energy, a bowling ball will go faster than a golf ball, because it has more mass.
Yes, because a bowling ball is more dense than a soccer ball. A bowling ball is solid all throughout while a soccer ball has its outer layer, but has air inside of it. Hope that this answer helps! :)
The object with the most gravitational force would be the bowling ball, as it has the greatest mass compared to a sand grain, marble, and tennis ball. Gravitational force increases with mass, so the object with the highest mass will have the strongest gravitational force.

In deep space, free of other gravitational influences, theoretically, yes. All objects with mass have "gravity" -- as long as the bowling ball contains more mass, there ought to be a particular velocity at which a golf ball would orbit it.
The bowling ball has more momentum because momentum is directly proportional to an object's mass and velocity. Since the two balls are moving at the same speed, the greater mass of the bowling ball results in it having more momentum.
Any amount of force can stop either kind of ball. But a greater force is required to stop a bowling ball than to stop a soccer ball IN THE SAME TIME, because the bowling ball has more mass, and therefore more momentum and more kinetic energy.
