A bowling ball keeps rolling down the alley because of
A
inertia
B
gravity
C
friction
D
mass
Explanation: 

Detailed explanation-1: -A bowling ball is also hard to stop. This is because of inertia. Inertia is the tendency for a moving object to keep moving and for an object at rest to remain at rest. Mass affects inertia.

Detailed explanation-2: -fk Mg When the ball is slipping, the forces acting on it are: 1) Weight Mg, acting vertically downward through the centre, 2) Normal reaction N, vertically upward through the point of contact 3) Forces of kinetic friction, fk = µN, horizontally through the point of contact and opposite to the direction of motion.

Detailed explanation-3: -Which object has more inertia and why? A bowling ball at rest or a high-speed soccer ball? Soccer ball. Because it is moving with a high velocity.
