Across
- 3. change in an object’s position or location
- 6. is the tendency of all objects to resist change in motion dependent on mass, to keep doing what they are already doing
- 10. is the rate at which velocity changes (speed or direction) over time as a result of unbalanced forces and mass of the object.
- 11. support force of a surface an object is in contact with preventing it from falling
- 12. is the sum of all forces acting on an object within a system, includes both magnitude (strength) and direction
- 13. group of items interacting to form a unified whole
- 15. 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
- 18. is speed that is steady or unchanging
- 19. net force greater than zeros that cause changes in motion of an object in the direction of the greater force
- 21. stored energy of an object due to position, condition, or composition (ex: chemical energy can be food, propane gas, or batteries)
- 22. is total distance traveled divided by total amount of time
- 23. Newton’s Third Law states that all forces occur in contact pairs where every action force has a reaction force that is equal in strength and opposite in direction.
- 24. Newton’s Second Law of motion states that the acceleration of an object depends on its mass and the amount of force applied where F = ma, objects accelerate in the direction of the unbalanced force. Acceleration is proportional to force but inverse to mass
Down
- 1. any push or pull between two objects, measured in Newtons (N)
- 2. energy of objects in motion.
- 4. is speed in a given direction
- 5. forces acting on an object that cancel each other out causing a net for of zero and causing no change in movement
- 7. unit of measurement of force (N)
- 8. three principles that explain the relationship between an object's motion and the forces applied to it; at least two laws always apply
- 9. a force acting directly in contact with an object
- 14. is the rate of change at which an object moves a distance over time
- 16. is the amount of matter in an object measure in grams or kilograms
- 17. Newton’s First Law states that an object's motion will not change unless an unbalanced force acts on it. Meaning if an object is moving it stays moving at the same speed and direction until forced to change
- 20. 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.
