Across
  1. 5. A type of collision where the total kinetic energy is conserved before and after the impact.
  2. 8. The change in momentum of an object when a force is applied over a period of time.
  3. 9. A principle stating that the total momentum of a closed system remains constant if no external forces act on it.
  4. 11. The product of an object's mass and its velocity, indicating the quantity of motion of the object.
  5. 12. A group of interacting or interdependent elements forming a complex whole, often considered in analyzing conservation laws.
  6. 14. An event where two or more bodies exert forces on each other for a relatively short time.
  7. 16. A physical system that does not exchange any matter with its surroundings and is not subject to any force whose source is external to the system.
  8. 17. In the context of collisions, this term refers to the degree to which objects “bounce back” after a collision, which is related to whether a collision is elastic or inelastic.
  9. 19. The duration over which force is applied, relevant in the calculation of impulse.

  1. 1. This law states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F=ma). It's foundational for understanding how forces affect motion and momentum.
  2. 2. While focusing on momentum, it’s also helpful to understand the conservation of energy, as energy and momentum are often discussed together, especially in collision scenarios.
  3. 3. The speed of an object in a particular direction.
  4. 4. The energy of an object due to its motion.
  5. 6. A collision in which part of the kinetic energy is converted to other forms of energy, such as heat or sound.
  6. 7. A physical system that exchanges both matter and energy with its surroundings. In terms of momentum and impulse, an open system is influenced by external forces and the addition or removal of mass, which can result in changes to the system's total momentum.
  7. 10. A push or pull upon an object resulting from the object's interaction with another object.
  8. 13. The quantity of matter in a body regardless of its volume or any forces acting on it.
  9. 15. States that for every action, there is an equal and opposite reaction.
  10. 18. Momentum and velocity are vector quantities, meaning they have both magnitude and direction. Understanding vectors is crucial for analyzing motion and forces.
