Across
- 4. A measure of the amount of matter in an object
- 10. the rate at which speed changes caused by the forward force being greater than the backwards force
- 14. A physical quantity that has magnitude only.
- 15. How far an object moves
- 16. a vector that represents the sum of two or more vectors
- 20. the ratio of the magnitude of the force of friction between two objects in contact to the magnitude of the normal force with which the objects press against each other
- 22. friction that occurs as an object moves through a fluid
- 24. A unit of measure that equals the force required to accelerate 1 kilogram of mass at 1 meter per second per second
- 26. a type of fluid friction, occurs as objects move through the air.

Down
- 1. a²+b²=c²
- 2. a friction force that acts on objects that are not moving
- 3. Forces that produce a nonzero net force, which changes an object's motion
- 5. A method of writing or displaying numbers in terms of a decimal number between 1 and 10 multiplied by a power of 10.
- 6. A push or pull exerted on an object
- 7. A series of steps followed to solve problems including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions.
- 8. A force that pulls objects toward each other and is affected positively by mass and negatively by distance.
- 9. Equal forces acting on an object in opposite directions (net force = 0 )
- 11. friction that occurs when an object rolls over a surface
- 12. The overall force on an object when all the individual forces acting on it are added together
- 13. how close a measurement is to the true value
- 17. the speed of an object at one instant of time
- 18. A quantity that has magnitude and direction
- 19. A measure of the force of gravity on an object; varies with the strength of the gravitational field.
- 21. friction that occurs when one solid surface slides over another
- 23. A part or element of a larger whole.
- 25. The force that two surfaces exert on each other when they rub against each other.
