Across
  1. 7. A machine that consists of two or more simple machines working together (e.g., a wheelbarrow or a pair of scissors).
  2. 9. The energy transferred when a force causes an object to move a distance. Calculated as Force × distance (W=Fd).
  3. 11. States that for every action, there is an equal and opposite reaction.
  4. 13. The tendency of an object to resist a change in its state of motion (speed or direction). It is directly proportional to an object's mass.
  5. 15. to protect oneself and equipment from risk and harm when using the internet, software, and external storage devices.
  6. 17. States that an object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.
  7. 18. A fundamental device that performs work by increasing or changing the direction of force, making work easier, but without changing the total amount of work done.
  8. 19. Physical deliverables or work samples created during the Create step of the EDP.
  9. 20. The first step of the EDP; involves defining the problem, identifying objectives, and determining challenges/limitations.
  10. 21. The standard unit of measurement for Work. (Named after James Prescott Joule).
Down
  1. 1. A force acting on an object that is not canceled out by other forces, causing the object to accelerate (change speed or direction).
  2. 2. The step of the EDP where the prototype is tested and analytical calculations and data are collected and analyzed.
  3. 3. States that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).
  4. 4. The standard unit of measurement for Force. (Named after Isaac Newton).
  5. 5. A restriction or limitation on a design (e.g., budget, time, materials, size).
  6. 6. A decision-making process during the Improve step where one desired feature is exchanged for another (e.g., increasing speed in exchange for reducing stability).
  7. 8. Malicious software designed to damage or gain unauthorized access to a computer system, often carried by unknown downloads or external drives (like USBs).
  8. 10. A simple machine (a ramp) that reduces the force needed to move an object but requires the object to travel a longer distance.
  9. 12. Practices to prevent hazards like fire or shock, requiring the first action in an emergency (like a burning smell) to be disconnecting the power source.
  10. 14. Any push or pull that can cause an object to accelerate. Calculated as mass × acceleration (F=ma).
  11. 16. A simple machine that is essentially an inclined plane wrapped around a cylinder.
