## What factor S would cause the bocce ball to move backward after colliding with the hollow plastic ball?

Critical Thinking Velocity would be the single most important factor. If the hollow plastic ball moves with a large velocity and hits the bocce ball head-on, and if the bocce ball’s velocity at the time of collision is v 0, then the bocce ball will reverse direction.

## When Mass is multiplied by velocity The answer is a measure of?

If the mass of an object is m and it has a velocity v, then the momentum of the object is defined to be its mass multiplied by its velocity. Momentum has both magnitude and direction and thus is a vector quantity. The units of momentum are kg m s−1 or newton seconds, N s.

## Can the moment of inertia of a fixed solid object be changed?

The moment of inertia of a fixed, solid object cannot be changed. 16. Linear momentum is the product of the moment of inertia and angular velocity for a rotating object.

## What happens if you hit the back wall in bocce?

If the thrown bocce ball hits the back wall, it is immediately removed from play. If the thrown bocce ball that first struck the back wall hits another bocce ball, the other bocce ball is returned as close as possible to its original position.

## What happens if both teams bocce ball are equal distance from the pallina?

In the event that the closest ball of each team is the same distance from the pallina, no points will be awarded and the pallina returns to the team that delivered it. Only balls which are distinguishably closer to the pallina than any of the opponent’s balls are awarded points.

## Which two factors could affect the amount of kinetic energy of a moving object?

Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed.

## What happens to K if velocity is tripled?

If the velocity (v) is tripled, the kinetic energy becomes, K′=21m(3v)2=9×21mv2=9K.

## What happens if velocity is tripled?

Since velocity is squared in the equation and if velocity triples, kinetic energy will increase by a factor of nine.

## What happens when 2 objects collide?

In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).

## Why is momentum called P?

The origin of the use of p for momentum is unclear. It has been suggested that, since m had already been used for “mass”, the p may be derived from the Latin petere (“to go”) or from “progress” (a term used by Leibniz).

## What happens to mass if velocity is doubled?

Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum.

## Can an object rotate without torque?

Not necessary; because for uniform rotational motion (i.e., angular acceleration α=0) any torque is not necessary. Torque is necessary to produce angular acceleration.

## Does moment of inertia depend on mass?

Moment of inertia of a body depends on the mass of the body, distribution of mass in the body, position of axis of rotation of the body and also depends on the distance of body from the axis of rotation.

## What is the SI unit of moment of inertia?

The SI unit of moment of inertia is kg. m2.

## What does kiss mean in bocce?

If a bocce ball is touching the pallino, its often known as a “baci” or “kiss” and can be rewarded 2 points if they remain touching at the end of the frame. The first team to reach 12 points wins the game (must win by 2).

## Do you roll or toss a bocce ball?

In bocce ball, there are typically two different techniques to throw, or roll, a ball: overhand and underhand. Whichever grip you choose, make sure to keep your fingers spread across the ball and maintain a reasonably tight grip on the ball. Swing your arm down and back from the side of your body.

## Can you go over 11 in bocce?

An end is over when all 8 balls have been thrown at the pallino and the score is counted. The player or team with the highest number of points after 11 ends wins the game. In open bocce, the style that we play, the game goes wherever the pallino is thrown.

## What happens if you hit the jack in bocce?

The player that threw the jack will throw the first bocce ball. After the first bocce ball is thrown, the opposing team will throw a bocce ball. The two teams will continue to alternate throwing bocce balls until all have been thrown.

## Can you throw a bocce ball in the air?

Player movements are limited by the foul line. The player may step on but not over the foul line before rolling the pallino or bocce ball. In the interest of safety, tossing the bocce ball in the air beyond the center of the court is never allowed. Only the inside team scores.

## Do you alternate throws in bocce?

Generally, everyone agrees on where it is fair to stand. The team that threw the pallino throws the first bocce. Teams and players alternate throws until all eight balls have been thrown. Players try to make their team’s bocce be the closest to the pallino.

## What is the most important factor controlling kinetic energy?

The most important factors that determine kinetic energy are the motion (measured as velocity) and the mass of the object in question.

## Does kinetic energy increase with height?

Contrary to potential energy, the kinetic energy of an object is relative to other stationary and moving objects present in its immediate environment. For instance, the kinetic energy of the object will be higher if the object is placed at a greater height.

## Which object has more potential energy?

Higher objects (with further to fall) have greater potential energy. The heaviest of 2 objects at the same height has the greatest gravitational potential energy.

## What happens to velocity when acceleration is maximum?

So, when velocity is maximum, acceleration is minimum (zero).
