Vocabulary set 3

3. relates forces between objects; when an object exerts a force on the 2nd object, the 2nd object exerts an equal amount of force in the opposite direction of the 1st object. (For every action there is an equal and opposite reaction); often applies to force pairs.
5. force that acts against the flow of electricity:R
8. forces experienced by an object when it is traveling in a curved path or circle.
9. a closed loop through which chargers can continuously move
11. measure of how strong a current in a circuit is;pressure:V-IR
13. measure of how hard it is to stop a moving object
14. electrochemical cell that converts chemical energy into electrical energy
16. instrument used to find the direction of a magnetic field

1. describes the relationship between an object’’s mass and acceleration based on the force applied to it; F=ma
2. object with an unequal number of protons and electrons
4. provides information about the =direction and strength of an electric field within a region of space
6. some of the kinetic energy gets converted to other forms like sound or heat energy
7. total kinetic energy and momentum before and after teh collision are the same
8. flow of electrical charge carriers:I
10. an object at rest will stay at rest and an object in motion will stay in motion (in a straight line at the same velocity unless acted upon by an outside force.)
12. tendency of an object to resist change in its motion (why we move forward with the car when it slams on breaks)
15. when 2 objects run into each other
