- 3. Scientific term to describe the point an object rotates about. Commonly called a pivot
- 6. In scientific investigations: the variable which is changed
- 10. The force experienced by an object moving through air
- 12. A measure of how tightly matter is packed into any material
- 15. A unit measurement of force
- 18. When two forces are acting on the same object but in opposite directions so that they cancel each other out
- 19. To make a physical or mental effort
- 21. A pushing force that results in a solid object shrinking
- 22. The force that enables us to stay on the ground
Down
- 1. A force pushing two objects away from each other
- 2. A force that pushes upwards on any object immersed in a fluid
- 4. An example of a second order lever
- 5. A quantity that can be altered or controlled, usually in an experiment
- 7. A scientific investigation in which one variable is changed, one is measured or observed and all other variables are kept the same
- 8. A simple device involving a solid arm and a pivot, or fulcrum, and which can move to multiply a force applied to one part
- 9. A scientific drawing using force arrows to show all the forces acting on an object
- 11. The input force to a lever
- 13. A force that makes an object move forwards
- 14. In scientific investigations: the variable which is measured
- 16. A resisting force acting between two surfaces in contact
- 17. The amount of matter in an object. Usually measured in kilograms
- 20. A resistive force that results when a substance moves through a fluid (air, water)
