Question

quiz 6.2.1 - energy forms
value: 16
match the description to the energy type.
a. a rise in temperature causes atoms and molecules to move faster and collide with each other.
b. energy that is used through the fission and fusion process.
c. energy caused by electrons.
d. energy held by an object when it is in a high position compared to a lower position.
e. form of potential energy which allows objects to be stretched and squashed.

1. elastic energy
2. thermal energy
3. gravitational energy
4. nuclear energy
5. electrical energy

Explanation:

• For "a": Thermal energy is related to the motion of atoms/molecules due to temperature, so a matches 2 (Thermal energy).
• For "b": Nuclear energy involves fission and fusion, so b matches 4 (Nuclear energy).
• For "c": Electrical energy is caused by electrons, so c matches 5 (Electrical energy).
• For "d": Gravitational energy depends on an object's height (position), so d matches 3 (Gravitational energy).
• For "e": Elastic energy is potential energy for stretched/squashed objects, so e matches 1 (Elastic energy).

Answer:

1. Elastic energy - e
2. Thermal energy - a
3. Gravitational energy - d
4. Nuclear energy - b
5. Electrical energy - c
