  1. 5. the rate of change of an object's velocity with respect to time, representing how quickly an object speeds up, slows down, or changes direction.
  2. 6. an event where two or more bodies move, interact, and exert strong, short-lived forces on each other, often exchanging momentum and kinetic energy.
Down
  1. 1. reduction in volume or size of a solid, liquid, or gas caused by applying inward-acting forces, which increases density and stress within the material.
  2. 2. the principle that specific, measurable properties of an isolated system—such as energy, momentum, or charge—remain constant over time, neither created nor destroyed, only transformed or transferred.
  3. 3. the measure of an object's motion
  4. 4. a push or pull interaction between objects that causes a change in motion, velocity, or shape
