physics key vocab
Across
- 1. the rate of change of a scalar field with respect to distance, in the direction of the maximum change
- 3. an influence that can cause an object to change its velocity unless it is counterbalanced
- 5. the speed in combination with the direction of motion of an object
- 9. the stored energy an object or system possesses due to its position or configuration, often associated with the potential to do work
- 11. the natural tendency of objects in motion to stay in motion and objects at rest to stay at rest, unless a force causes the velocity to change
- 13. measures the length between objects or points without regard for direction
- 14. a form of energy that an object or a particle has by reason of its motion
- 15. a measure of how much matter there is in an object
- 17. a particular measurable property of an isolated physical system does not change as the system evolves over time
- 18. a comparison of the energy output to the energy input in a given system
Down
- 2. the rate of change of an object's velocity over time
- 4. a fundamental force of attraction that exists between any two objects with mass
- 6. a state where a system experiences no change in its motion or internal energy
- 7. the vector sum of two or more vectors
- 8. the shift in location when an object in motion changes from one position to another
- 10. the magnitude of the change of its position over time
- 12. a measure of the size of the pull of gravity on an object
- 16. the ability to do work
