Across
- 3. a scalar quantity that refers to "how fast an object is moving"; the rate at which an object covers distance
- 7. the location of something relative to something else; compares the position of something to another object, such as up, down, in, out, left, right, forward, backward, or sideways
- 8. _______ distance is the distance that a vehicle travels while slowing to a complete stop
- 10. a measurement of mass in motion: how much mass is in how much motion
- 12. an encounter (collision) between two bodies in which the total kinetic energy of the two bodies remains the same
- 15. the tendency of objects in motion to stay in motion, and objects at rest to stay at rest, unless a force causes its speed or direction to change
- 17. a quantity that has both magnitude and direction
- 18. the total momentum of the two bodies remains the same, but some of the initial kinetic energy is transformed into heat energy
- 20. ability to do work, which is the ability to exert a force causing displacement of an object
- 23. ________ time the amount of time it takes for a person to respond to a stimulus; it is often measured in seconds or milliseconds
- 24. energy that has the potential to become another form of energy
Down
- 1. a vector quantity that designates how fast and in what direction a point is moving
- 2. the measure of the amount of matter in a body
- 4. reaction ________ is the ________ you travel from the point at which you detect a hazard until you begin braking or swerving
- 5. three words combined into one; a useful aid for representing the relative magnitude and direction of all forces acting upon an object in a given situation
- 6. “distance or quantity.” It is used to express the size or scope of something
- 9. The push or pull on an object with mass that causes it to change its velocity; an external agent capable of changing a body's state of rest or motion. It has a magnitude and a direction (vector)
- 11. the force exerted on a body by gravity
- 13. any item, factor, or condition that can be controlled, changed, or measured
- 14. the form of energy that an object possesses due to its motion
- 16. The rate of change of velocity with respect to time; a vector quantity as it has both magnitude and direction
- 19. the traditional mathematical sign for representing a change as well as variation in some kind of quantity or object; Δ
- 21. the product of the force strength and the distance traveled
- 22. a physical quantity that is completely described by its magnitude. Examples are volume, density, speed, energy, mass, and time
