Across
- 7. A machine that consists of two or more simple machines working together (e.g., a wheelbarrow or a pair of scissors).
- 9. The energy transferred when a force causes an object to move a distance. Calculated as Force × distance (W=Fd).
- 11. States that for every action, there is an equal and opposite reaction.
- 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.
- 15. to protect oneself and equipment from risk and harm when using the internet, software, and external storage devices.
- 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.
- 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.
- 19. Physical deliverables or work samples created during the Create step of the EDP.
- 20. The first step of the EDP; involves defining the problem, identifying objectives, and determining challenges/limitations.
- 21. The standard unit of measurement for Work. (Named after James Prescott Joule).
Down
- 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. The step of the EDP where the prototype is tested and analytical calculations and data are collected and analyzed.
- 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. The standard unit of measurement for Force. (Named after Isaac Newton).
- 5. A restriction or limitation on a design (e.g., budget, time, materials, size).
- 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).
- 8. Malicious software designed to damage or gain unauthorized access to a computer system, often carried by unknown downloads or external drives (like USBs).
- 10. A simple machine (a ramp) that reduces the force needed to move an object but requires the object to travel a longer distance.
- 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.
- 14. Any push or pull that can cause an object to accelerate. Calculated as mass × acceleration (F=ma).
- 16. A simple machine that is essentially an inclined plane wrapped around a cylinder.
