2 Formula SPEED

3 What is Work? When a force is applied to an object to move a distance

4 Formula SPEED

5 What is Kinetic energy? Energy of any matter in motion

6 What is Potential energy?
The energy of position This is energy not yet in motion

7 Formula SPEED

8 What is Electromagnetism?
Energy that comes from positive and negative parts of atoms Examples: Static shock & lightening

9 Formula SPEED

10 What is Nuclear Energy? Fusion : Energy produced when atoms come together Fission : Energy produced when an atoms splits apart.

11 Formula SPEED

12 What is Chemical Energy?
Photosynthesis: sunlight & water used to make energy

13 Formula SPEED

14 What is Energy Exchange?
Transforming one form of energy into another form. Water power, Nuclear power, wind power become electricity

15 Formula SPEED

16 What are the three laws of Thermodynamics?
#1: Energy cannot be created nor destroyed #2: Energy never flows from colder to hotter. #3: Energy travels slower the colder it gets.

17 Formula SPEED

18 What is E = MC2? Energy = Mass X Speed of light 2 Matter & energy are different aspects of the same thing

19 Formula SPEED

20 Energy can be created and sometimes destroyed?
FALSE

21 The formula physicists use to express the expenditure of work or energy is?
Work = total force X distance traveled

22 Kinetic Energy is described as energy of matter in motion?
TRUE

23 Potential Energy is not important in the total amount of energy available in the universe?
FALSE

24 Electromagnetic energy only exists as radiant energy from the sun and stars?  
FALSE

25 Under intense heat two hydrogen isotopes will fuse to form a helium atom and release energy. This process is called?   FUSION

26 Photosynthesis is a process that coverts the sun into chemical energy in the leaves of plants?
TRUE

27 Energy can be changed or recycled from one form to another?
TRUE

28 The second law of thermodynamics concludes that all things are moving towards?
EQUILIBRIUM

29 Einstein’s formula of E = MC2 states that energy equals mass times the speed of light squared?
TRUE
