1. Motion 1. An object's change in position relative to a reference point.
2. Reference Point 2. an object that appears to stay in place.
3. Speed 3. The distance traveled divided by the time interval during which the motion occured.
4. Velocity 4. The speed of an object in a particular direction.
5. Acceleration 5. The rate at which velocity changes overtime;an object accelerates if it's speed, direction, or both change.
6. Force 6. a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.
7. Newton 7. The SI derived unit used to measure force. One newton is equal to the force needed to accelerate a mass of one kilogram one meter per second per second.
8. Net force 8. The sum of all the forces acting on an object.
9. Balanced forces 9. two forces acting in opposite directions on an object, and equal in size. Anytime there is a balanced force on an object, the object stays still or continues moving continues to move at the same speed and in the same direction.
10. Unbalanced forces 10. Forces that cause a change in the motion of an object.
11. Energy 11. In physics, the ability to do work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another.
12. Potential energy 12. Stored energy that depends upon the relative position of various parts of a system.
13. Kinetic energy 13. The energy of a body in motion.
14. Energy Transformation 14. The process of changing energy from one form into another form.
