# A bowling ball with a negative initial velocity slows down as it rolls down the lane toward the pins Is the bowling ball's acceleration positive or negative as it rolls toward the pins?

In these situations, you usually define one direction as being positive and the other as negative. In this problem, the question does this for us: it clearly tells us that when the ball is moving down the lane, its velocity is negative. "Down the lane" is the negative direction.

Average acceleration is give by

a_ave = Δv/Δt

where Δv is a change in velocity and Δt is elapsed time.

Δv = v_final - v_initial

In this problem, the ball "slowed down," but did not change direction. This means that the NUMBER associated with "v" got smaller (5 ... 4 ... 3 ...) but the SIGN (-) did not change.

I hope it makes sense, then, that "v_final" was a smaller (slower) number with a negative sign (moving down the lane) while "v_initial" was a larger (faster) number with a negative sign (moving down the lane).

The subtraction of a large negative number from a small one (like, for instance, -4 - [-10]) is a POSITIVE number whose value is given by the difference (+6).

So Δv is positive, and Δt is ALWAYS positive (no matter what).
Therefore a_ave, the quotient of two positive numbers, will be positive.

### When did High Velocity Bowling happen?

High Velocity Bowling happened in 2007.

### Are bowling scores and golf scores positive or negative correlations?

Bowling scores would be a positive correlation because the higher the score, the better the game. Golf scores would be negative correlations because the higher the score, the worse you are playing.

### When was High Velocity Bowling created?

High Velocity Bowling was created on 2007-12-07.

### How much force N is needed to knock over a bowling pin?

It typically takes about 110-130 Newtons of force to knock over a standard 15-inch-tall bowling pin. This force can vary depending on factors such as the weight of the bowling ball and the angle at which it strikes the pin.

### What actors and actresses appeared in High Velocity Bowling - 2007?

### Is negative eight in bowling good or bad?

A negative eight in bowling is impossible. The lowest score one can have for a game is 0.

### Why does a bowling ball move without acceleration when it rolls along a alley?

Strictly speaking, it moves with negative acceleration. The forces of friction and air resistance both act to slow the ball down. If the lane were long enough, the ball would eventually come to a complete stop.

### Examples where velocity is zero but not acceleration?

An object in free fall at its peak point has a velocity of 0, but there is still acceleration acting on it due to gravity. Similarly, a pendulum at the extreme points of its swing also has zero velocity but is undergoing acceleration towards the center of its swing.

### What are some real life examples of Newton's second law of motion?

The second law of motion states that the acceleration of the an object depends on the mass of the object and the size of the force acting on it a good example is bowling because the acceleration of the bowling ball hitting the pins are hitting the shape and the size of it. And the force acting on it is the bowling ball and bowling pin that is an example of the second law of motion.

### Does a bowling ball have more force than a feather?

Well according to the equation Force = Mass x Acceleration. A bowling ball has more mass than a feather but it all depends on how much acceleration each is undergoing. Potentially a feather can have more force (if the bowling ball has an acceleration of zero, then there is no force being produced, and if the feather is accelerating at any speed greater than zero, thentechnicallyit has more force)

### What is the weight in newtons of a 9.5 kg bowling ball?

The weight of a 9.5 kg bowling ball can be calculated using the formula: weight = mass * acceleration due to gravity. The acceleration due to gravity is approximately 9.81 m/s^2. Therefore, the weight of a 9.5 kg bowling ball is about 93.95 Newtons.

### How much force it needed to accelerate a 25 kg bowling ball at?

The force needed to accelerate a 25 kg bowling ball would depend on the desired acceleration. Newton's second law states that force equals mass multiplied by acceleration (F = ma). If you specify the acceleration, the force required can be calculated using this formula.
