Lesson 2 Reading Guide - KC

4. Changes Between Forms of Energy
The changes from one type of energy to another type of energy are called energy transformations.

5. Radiant means transmitted by electromagnetic waves
A microwave oven changes electric energy into radiant energy.

Lesson 2-1

6. Changes Between Kinetic and Potential Energy
1. Energy changes between kinetic energy (KE) and potential energy (PE) when a ball is thrown and moves upward and then downward.
Lesson 2-2

7. 2. As the ball moves upward, its speed and kinetic energy decrease, but the potential energy is increasing because the ball’s height is increasing.
3. At the ball’s highest point, the gravitational potential energy is greatest, and the ball’s kinetic energy is the least.
Lesson 2-2

8. 4. As the ball moves downward, potential energy decreases
4.As the ball moves downward, potential energy decreases. At the same time, the ball’s kinetic energy increases.
5. When the ball reaches the player’s hand again, its kinetic energy is at the maximum value again.
Lesson 2-2

9. The Law of Conservation of Energy
According to the law of conservation of energy, energy can be transformed from one form into another or transferred from one region to another, but energy cannot be created or destroyed.
Lesson 2-3

10. a cooler place to a hotter one
Heat won’t pass from
a cooler place to a hotter one
The energy content of the universe is always diminishing in quality.

11. The Law of Conservation of Energy (cont.)
Friction is a force that resists the sliding of two surfaces that are touching.
Lesson 2-3

12. Friction and the Law of Conservation of Energy Discuss this in pairs:
What happens to mechanical energy when you apply the bicycle brakes and the bicycle stops?
A moving bicycle has mechanical energy. When you apply the brakes, is the bicycle’s mechanical energy destroyed?
Lesson 2-4

13. Friction and the Law of Conservation of Energy (cont.)
Friction between the brake pad and the moving wheel transforms mechanical energy into thermal energy.
There is always friction between any two surfaces that are rubbing against each other.
Lesson 2-4

14. When you use energy, you usually change it from one form into another.
Using Energy
When you use energy, you usually change it from one form into another.
All forms of energy can be transformed into thermal energy.
During photosynthesis, a plant transforms the Sun’s radiant energy into chemical energy that it stores in chemical compounds.
Lesson 2-4

16. Using Energy, Heat and Waste
When energy changes form, some thermal energy (heat) is always released.
Scientists often refer to thermal energy that cannot be used as waste energy.
Whenever energy is used, some energy is transformed into useful energy and some is transformed into waste energy.
