Across
- 2. A scalar quantity (magnitude only) measuring the total path length an object takes to get from an initial point to a final point.
- 3. A pulling force that a rope or other flexible material exerts or carries.
- 4. A scalar quantity and the rate at which an object moves a distance.
- 5. A resistive force that opposes the motion of objects that touch and move relative to each other. When an object moves in one direction, the force moves in the opposite direction.
- 10. An object’s property that makes the object resist changing its state of motion. More massive objects have more of this property.
- 11. Measures how much gravity pulls an object and changes according to an object’s location. Can be found by multiplying an object’s mass with the acceleration due to gravity at the object’s location.
- 15. A force an object generates by pushing or accelerating air. When the gas is pushed in one direction, the force moves the object in the opposite direction.
- 18. The energy that an object has gained from moving to an elevated position.
- 20. An object that moves because of and only experiences the force of gravity and no other forces.
Down
- 1. The net force acting on an object is the product of the object’s mass and acceleration.
- 6. Requires an unbalanced force to happen and describes the rate at which velocity changes for an object. An object undergoes this process when changing directions, speeding up, or slowing down.
- 7. When two objects act on each other, the magnitude of the forces they exert on each other is the same, but the directions of their forces are opposite to one another. The first action force will always experience a reaction force.
- 8. The energy that an object has because the object is moving.
- 9. Unless experiencing an unbalanced force, an object will keep its original state of motion, such as staying still or moving in a straight line at a constant rate.
- 12. A force that stops an object from passing through another solid object and acts perpendicular to a surface.
- 13. An attractive force existing between objects with mass. Causes objects on Earth to accelerate at 9.8 meters/second^2 toward the center of the Earth.
- 14. A vector quantity (magnitude and direction) indicating how far an object has moved from an initial position, regardless of how much the object traveled to reach the final position.
- 16. A vector quantity describing the rate of displacement for an object.
- 17. An object’s amount of matter. Does not automatically change when the object’s location changes. Objects with more of this quantity have more inertia.
- 19. A vector diagram depicting an object and the magnitude and direction of the forces that act on the object.
