Question

1. from \kinetic energy\...kinetic energy can: (6 points)

become potential energy during a collision
decrease during a collision
increase during a collision
be transferred between objects during a collision

1. from \mechanical energy\...when a force acts on an object causing it to move, change shape, or in some way be displaced, it is called: (6 points)

mechanical energy
work
kinetic energy
potential energy

Explanation:

For question 12: Kinetic energy can convert to potential energy (e.g., when objects bounce and gain height), decrease (in inelastic collisions with energy loss to heat/sound), increase (if an external force adds energy during collision), and transfer between colliding objects (like in billiard balls). All these scenarios are physically valid.
For question 13: The scientific definition of work is when a force acts on an object to cause displacement (including movement or shape change), which matches the description.

Answer:

12.

• become potential energy during a collision
• decrease during a collision
• increase during a collision
• be transferred between objects during a collision

1. work
