ENERGY AND FORCES UNIT TEST CONNECTIONS ACADEMY

Answer 1

Explanation:

1. at least two charged, interacting parts
2. from the electric fields of charged molecules
3. an arrow released from the bow
4. Electrical fields of charged particles interact, bonding those with opposite charges.
5. the interaction of the electric fields of protons and electrons
6. The energy stored in the system first increases and then decreases.
7. Kinetic energy decreases because the magnets move in the direction of the field.
8. Iron pieces accelerate toward the magnet, and the energy stored in the system decreases.
9. The energy stored in the field increases because the magnet moves in the direction of the field.
10. The energy stored decreases.
11. it is not sure.

Answer 2

Answer:

1. at least two charged interacting parts

2. from the electric fields of charged subatomic particles

3 an arrow released from the bow

4Electrical fields of charged particles interact, bonding those with opposite charges.

5 the interaction of the electric fields of protons and electrons

6 The energy stored in the system increases.

7 Kinetic energy increases because the magnets move in the direction of the field.

8 Iron pieces accelerate toward the magnet, and the energy stored in the system decreases.

9  

The energy stored in the field decreases because the magnet moves in the direction of the field.

10 The energy stored increases and then decreases.

11 The wire was not connected to the source.

12  The electromagnet will become more powerful.

the rest are written, hope this helps (:
