Across
- 2. any push or pull between two objects, measured in Newtons (N)
- 4. is the tendency of all objects to resist change in motion dependent on mass, to keep doing what they are already doing
- 5. is the rate at which velocity changes (speed or direction) over time as a result of unbalanced forces and mass of the object.
- 9. a force acting directly in contact with an object
- 10. group of items interacting to form a unified whole
- 14. net force greater than zeros that cause changes in motion of an object in the direction of the greater force
- 15. is total distance traveled divided by total amount of time taken
- 17. three principles that explain the relationship between an object's motion and the forces applied to it; at least two laws always apply
- 20. gravity is the pull toward another object based on its mass. Gravity is constant meaning it is always pulling objects down at 9.8m/s2
- 22. speed in a given direction
- 23. is speed that is steady or unchanging
Down
- 1. newtons first law
- 3. is the sum of all forces acting on an object within a system, includes both magnitude (strength) and direction
- 6. newtons third law
- 7. newtons second law
- 8. stored energy of an object due to position, condition, or composition (ex: chemical energy can be food, propane gas, or batteries)
- 11. is the rate of change at which an object moves a distance over time
- 12. energy of objects in motion
- 13. forces acting on an object that cancel each other out causing a net for of zero and causing no change in movement
- 16. support force of a surface an object is in contact with preventing it from falling
- 17. unit of measurement of force (N)
- 18. is the amount of matter in an object measured in grams or kilograms
- 19. change in an object’s position or location
- 21. is a force that is opposite of motion between two surfaces that are touching causing it to slow down. A frictionless surface will not affect motion.
