## Why does the force of gravity do no work on a bowling ball?

A. The speeds of the bowling ball and the satellite are not affected by the force of gravity because there is no horizontal component of gravitational

## What forces act on a bowling ball?

The force of gravity is pulling the pins toward the center of the earth. The force of friction is helping to keep the pins from sliding off the lanes. When one force is greater than its opposite force , they are unbalanced forces . We rely on the unbalanced forces of the rolling ball to knock down the pins.

## Does a bowling ball exert a gravitational force?

A falling bowling ball has 160 times the gravitational force acting on it as compared to a golf ball . The weight force is greater. The bowling ball falls with an acceleration of 9.8m/s^{2} because its inertia (mass) is 160 times greater than a golf ball . It resists the greater pull of gravity .

## How can you apply the work energy theorem to lifting a bowling ball?

Work – Energy Theorem How can you apply the work – energy theorem to lifting a bowling ball from a storage rack to your shoulder? The bowling ball has zero kinetic energy when it is resting on the rack or when it is held near your shoulder. Therefore, the total work done on the ball by you and by gravity must equal zero.

## Under what condition does gravity do no work on a moving object?

Under what condition does gravity do not work on a moving object ? Gravity does no work on objects moving perpendicular to the gravity vector; in other words, the object is moving horizontally.

## What causes a bowling ball to hook?

The second way to produce a hook is by modifying the bowling ball . Illegally, one can play with the weighting of the bowling ball , such as drilling the ball so that there is more side weight on the right side of the ball (for a right-hander,) which would cause the ball to pull from right to left, causing a hook .

## Why is rolling a ball down a hill considered an unbalanced force?

Terms in this set (25) -An object at rest will remain at rest and an object in motion will remain in motion until an unbalanced force acts upon them. (Ex~A ball will roll down a hill , but will eventually stop because of friction.) -Gravity acts on objects at rest.

## Are bowling balls weighted to spin?

The alternate guideline states that a bowler should use a ball roughly 10% of their body weight , up to the 16 pound maximum size of the ball for those over 160 pounds in weight . It is important to use a ball of the appropriate weight in order to impart the necessary amount of spin .

## Why does a feather fall slower than a brick?

Well, it’s because the air offers much greater resistance to the falling motion of the feather than it does to the brick . The air is actually an upward force of friction, acting against gravity and slowing down the rate at which the feather falls.

## Do heavier things fall faster?

They think that gravity acts more on a heavier object thus pulling it down faster . In fact, gravity works independently of mass. This means that all objects should fall at the same rate. If there is no air resistance, or the same amount of air resistance, then objects of the same mass will fall at the same rate.

## Do heavier objects roll faster?

After a two sample t-test, we find that heavier rolling objects have a statistically faster clear time for a given inclined plane in comparison to lighter rolling objects . In addition, heavier objects will be more resistant to the effects of air resistance and rolling resistance.

## What increases potential energy?

The heavier the object and the higher it is above the ground, the more gravitational potential energy it holds. Gravitational potential energy increases as weight and height increases . Potential energy is energy that is stored in an object or substance.

## How do you calculate work done?

Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work .

## What factors affect potential energy?

The factors that affect an object’s gravitational potential energy are its height relative to some reference point, its mass, and the strength of the gravitational field it is in.
