- 4. increase in the rate or speed of something.

- 10. the resistance that one surface or object encounters when moving over anothe
- 12. Law for every action (force) in nature there is an equal and opposite reaction
- 16. a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact
- 17. the moving of something from its place or position.
- 18. a tendency to do nothing or to remain unchanged

- 20. force opposite in direction and equal in size.
Down
- 1. Theory a structured explanation to explain a group of facts or phenomena in the natural world that often incorporates a scientific hypothesis and scientific laws
- 2. The push or pull on an object with mass causes it to change its velocity
- 3. a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses
- 5. resistance the force that the object experiences as it passes through the air.
- 6. an invisible force that pulls objects toward each other
- 7. the speed of something in a given direction.
- 9. the rate at which someone or something is able to move or operate.
- 11. the quantity of motion of a moving body, measured as a product of its mass and velocity.
- 13. the force acting on an object due to gravity.
- 14. Law the acceleration of an object is directly proportional to the net external force applied, and it is indirectly proportional to its mass
- 15. friction opposes the movement between two contact surfaces that slide against each other
