In a game of billiards, when a cue ball collides with another ball, what primarily dictates the change in motion of both balls immediately after impact?
- The brand of billiard balls being used.
- The amount of chalk on the tip of the pool stick.
- The color of the billiard balls involved.
- The transfer of energy and momentum between the balls. (correct)
If a cue ball strikes a stationary billiard ball, resulting in both balls moving, which of the following statements accurately describes the energy distribution immediately post-collision?
If a cue ball strikes a stationary billiard ball, resulting in both balls moving, which of the following statements accurately describes the energy distribution immediately post-collision?
- The struck ball gains more energy than the cue ball loses due to the conversion of sound energy into kinetic energy.
- The energy is equally divided between the cue ball and the struck ball, regardless of their masses.
- The cue ball retains all of its original kinetic energy, while the struck ball gains potential energy.
- The cue ball loses some of its kinetic energy, which is transferred to the struck ball causing it to move. (correct)
When setting up a domino run, how does adding a small, lightweight ball within the domino pattern affect the energy transfer, assuming the ball is placed in the path of falling dominoes?
When setting up a domino run, how does adding a small, lightweight ball within the domino pattern affect the energy transfer, assuming the ball is placed in the path of falling dominoes?
- It will have no effect on the overall energy transfer.
- It will absorb all the energy, stopping the domino effect.
- It will amplify the energy, causing the dominoes to fall faster.
- It requires additional energy to move, potentially altering the domino's momentum and the chain reaction. (correct)

Study Notes
- Energy can be transferred, or moved from place to place via objects that move and collide.
- The transfer of energy changes the way objects behave and releases new types of energy like sound and heat.
- A collision can cause a change in each object's motion.
Collision Defined
- A forceful impact in which energy is transferred from one object to another.
Collisions and Sound Production
- Energy from a moving hand is transferred to a front door when knocking.
- The hand's force moves energy into the door, causing it to vibrate.
- The energy passes to the air on the other side as vibrations, which is called sound.
- Even tiny collisions can cause sound.
- Electrons moving through power lines (electricity) create a humming sound by disturbing the air around the wires.
- If electricity stops flowing, the humming sound ceases.
Collisions and Heat Production
- When a match end collides and scrapes across the rough bumps on a box (a source of friction), it heats up and starts to burn.
- The scratching sound is produced from the collision between the match and the bumps on the box.
- Clapping hands together transfers energy, creating sound and heat due to the collision.
Collisions and Changes in Motion
- When objects collide, energy from one object's motion transfers to another.
- This energy transfer can cause the motion of the objects to change.
- When a cue ball strikes another ball, the collision transfers energy from the cue ball to the other ball.
- The cue ball slows down and could move in a different direction, while the other ball starts rolling, changing its motion.
Conservation and Transfer of Energy
- When a cue ball hits a group of billiard balls, there will definitely be a transfer of energy.
- The domino effect demonstrates transfer of energy that happens during collisions to create fun designs
- Energy is always conserved.
