Mechanical Energy Lesson 1: Kinetic Energy

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.

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.
