Across
- 4. Energy due to motion.
- 7. To become four times bigger in number or value.
- 11. A relationship where a change in one variable does not create a straight-line change in another; the changes may curve or vary unpredictably.
- 12. The variable that is changed or controlled in an experiment to test its effect on the other variables in the experiment.
- 16. Things that change at the same rate, maintaining the same relationship between them.
- 17. The ability to do work or cause change, such as moving an object or heating a substance.
- 18. The amount of matter in an object, which affects its kinetic energy.
- 19. A noncontact force that pulls objects toward each other due to their mass.
- 20. A mathematical relationship where the rate of change increases rapidly, such as kinetic energy increasing with the square of speed.
Down
- 1. A push or pull acting on an object, which can cause it to move, stop, or change direction.
- 2. The speed of an object in a specific direction.
- 3. The rate at which an object's velocity changes over time.
- 5. Related to a line, often describing a straight-line relationship.
- 6. The variable that is measured or observed in an experiment. This variable changes as the result of other variables scientists control.
- 8. Going side to side.
- 9. A force that resists the motion of two surfaces sliding against each other.
- 10. Going straight up and down.
- 13. Connected to or linked with something. (This appears in the text when describing how kinetic energy is related to mass and speed.)
- 14. A connection or link between two or more variables, objects, or processes, often showing how one affects or depends on the other.
- 15. The rate at which an object moves, which also determines its kinetic energy.
