Why does the force of gravity do no work on a bowling ball rolling down a bowling alley?

Work is definied in Physics as the Force acting on an object times the distance the object is moved by that Force, or W = fd
Since Force is mass times acceleration (F=ma), and because the ball is on a surface that is perpendicular to the force exerted by gravity, there is no gravitational acceleration (a), hence no Force, so no Work is done by gravity.

Ball rolling down a bowling alley and you'll find it moves slightly slower with time Does this violate Newton's law of inertia?
No it does not violate the law of inertia. This is because while a Bowling Alley is very smooth, it is not exactly frictionless, there is still some friction that acts on the ball, hence slowing it down. Newton said that a body will remain in its state or rest or of motion in a straight line provided there is NO other force acting on the body, but here, we do have a frictional force that acts on it.
Which of these uses the force of gravity to make it move?
Which of these uses the force of gravity to make it move
The force of gravity opposes what other force?
The force of gravity opposes acceleration away from the source of the gravity. This is expressed as "centrifugal force" or the perpendicular component of a tangential velocity. The balance between these keeps the planets in orbit around the Sun.
What is import force?
gravity
What is the mass of an object if the force of gravity acting on its mass is 1033 Newtons?
If we have a force acting on a body and we know what that force is, and we also know that the force is gravity, we can solve because we know the force gravity exerts on a mass. If we take the total force acting on the body and divide it by the force of gravity per one unit of mass, we can find the number of units of mass that cause gravity to act on the object. We have 1033 Newtons of force acting on the object. Gravity pulls down with a force of 9.8 Newtons on 1 kilogram of mass. Our 1033 Newtons divided by 9.8 Newtons per kilogram = 105.41 kilograms
What force acts on the bowling ball?
Gravity and normal force (floor pushing on the ball) if its already rolling. If it's being thrown, then gravity, normal force, and the hand throwing it.
What force slows a marble rolling on a flat surface?
Gravity!
What is the force that pulls all objects to the earth?
GRAVITY... 2nd answer: The force that pulls all objects toward each other is gravity. The earth exerts the force of gravity on you, and you exert the force of gravity on the earth ( or your couch, dog, etc). We notice Earth's force of gravity because it is huge compared with the force of gravity of our bodies .... or the force of gravity of our bowling balls, and so forth.
Does rolling soccer ball needs more force to stop than a rolling bowling ball?
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.

With how much force does a ramp push a ball rolling down it?
A ramp exerts no force, just gravity.
Will a16 lb bowling ball and a 10 lb bowling ball dropped together reach the ground together?
Yes... Its not the weight but the force of gravity
How much work does the force of gravity do on a 5.45-kg bowling ball that falls a distance of 0.755m?
41.1j
Describe a common situation in which the net force on an object is zero but the object is not at rest?
Bowling ball rolling down the lane.
Would a rock rolling down a hill be magnetic force?
No. A rock rolls down a hill due to the force of gravity, also known as gravitic force.
Why doesn't the force of gravity change the speed of a bowling ball as it rolls along a bowling lane?
Gravity most definatley works on a bowling ball as it goes down the lane. If gravity didn't affect it then the ball would go through the roof of the center. However the ball does not appear to slow down much because there is clear oil on the lane (in varying amounts) which allows the ball to skid across the lane without giving up a lot of speed.The ball is rolled down the lane with enough force to allow it to gain momentum (a sort of gravity) and the lane is heavily waxed, so there is little resistence to slow it down. The ball will sometimes 'break', or hook to the left or right; this makes the ball go into the 'gutter' if your ball doesn't have enough momentum. If you notice, on the lane before and after the foul line, there are arrows that guide where you stand and where you aim your ball to guide it so that the ball will turn left or right to hit the left or the right of the #1 pin to get a strike.Work is the force times the distance traveled in the direction of the force (vector multiplication). If the bowling alley is level, then as the ball moves it's distance from the center of the earth does not change. That is, it does not move at all in the direction of the force of gravity. Since the distance moved toward or against the force is zero, the work done is zero.Force of gravity will not effect the bowling ball because the Normal Force is equal to the Force of gravity. Therefore canceling each other out. The forces on the bowling ball rolling down a bowling alley would be Applied Force and some Force of Friction.Work (W) is defined in Physics as the Force (f) acting on an object times the distance (d) the object is moved by that Force, or W = fdSince Force is mass times acceleration, and because the ball is on a surface that is perpendicular to the force exerted by gravity, the ball does not move vertically; there is no gravitational acceleration, hence no Force, so no Work is done by gravity.
Is a rock rolling down a hill a natural force?
It involves the forces of Gravity. It also involves Friction and Inertia.
