Answer 1

Select these two responses:

- Kinetic energy can move from one item to another.
- Energy transfers from materials through touch.

Why: When a puck hits another object (or is struck by a stick), kinetic energy is transferred between the bodies by contact forces. Kinetic energy is not automatically “transferred through air when materials are close” (unless you mean losses to the air via drag or pressure waves), and kinetic energy is not always lost during transfer — some can be conserved (elastic collisions) while some can be converted to heat/sound in inelastic collisions.
