1. Introduction to Physics Lesson 15

2. Activator
15 minutes of silence (timer up, if students talk it is reset)
Read the article
Answer the 5 questions at the bottom
After the 15 min of independent work is up, take 5 min discuss your answers with a partner
We will discuss as a class after

3. Study of matter and energy Physicist are to find:
Physics
Study of matter and energy
Physicist are to find:
describe a complex universe with simple and useful clarifying laws
Define the most fundamental measurable quantities (velocity, electric field, kinetic energy)
Find relationships between those fundamental measured quantities (Newton’s Laws, conservation of energy, special relativity)

4. Energy is a measurement of the ability of something to do work
Energy and Work
Energy is a measurement of the ability of something to do work
Energy is never really destroyed
Transferred from one form to another

5. Work Force applied to object  object moves  work is done
If the object doesn’t move  no work
Force is applied and the object  moves a distance in a direction other than the direction of the force  less work is done

6. Measuring Energy and Work
Standard unit  joule (J)
Calorie
One Calorie is the amount of energy required to raise 1 kg of water by 1​ Celsius. 
The calorie, written with a lowercase c, is the amount of energy required to raise 1 gram of water by 1 Celsius.
The Calorie, written with a capital C, is the amount of energy required to raise 1 kilogram of water by 1 Celsius.

7. Calculating Force Work=Force x distance
Jimmy pushes a block 7 meters with a force of 10 Newtons. How much work did he do?
10N x 7M = 70 N per m or Joule
Finish the calculations on your worksheet.
15 minutes independently then compare answers with classmates.
