7. Physics

8. Physics is the study of matter and energy.

9. Name some types of energy.
Matter: Anything that has mass and occupies space.
Energy: The using of force to cause motion.
Name some types of energy.

10. Branches of Physics
Mechanics
Vibrations and Waves
Electromagnetism
Optics
Thermodynamics

11. Scientific Revolution
Physics as a science begins in the mid 1500’s into the early 1600’s.
Physics relates mathematics and reproducible experimentation to the study of matter and energy.

12. Galileo Galilei ( )

13. Birthplace of Galileo?
Pisa!!

14. Basic Units of Measurement
Mass : kilograms (kg)
Distance/Length : meters (m)
Time : seconds (s)

15. Metric System
The metric system allows you to convert from small to large units simply by moving the
decimal point.

16. 100 cm =
1 m
2 m =
200 cm
1 km =
1000 m
200 m =
0.2 km
3 kg =
3000 g
1500 g =
1.5 kg

17. Metric prefixes in everyday use
Prefix Symbol Factor Power
tera- T x1012
giga- G x109
mega- M x106
kilo- k x103
(none) (none) x100
centi- c x10-2
milli- m x10-3
micro- μ x10-6
nano- n x10-9

18. Use conversion factors to convert one unit to another.
Make sure the units you want to get rid of cancel out.

19. To convert 1 year to seconds 4 conversion factors are needed.
= 3.15x107 s

20. Convert 5 km/h to m/s. 5 km 1 h = 1.39 m/s 1000m 1 h 1 min _________X X X
1 h
1km
60 min
60 s
= 1.39 m/s
