What to Reviewfor the

Final Exam

Physics I

1st Semester

2013-14

The Final Exam is Worth

20% of your

Semester Grade

The final exam is comprehensive, meaning it

will cover the entire semester.

What to Bring

• Calculator

• #2 Pencil

• Note Page (81/2” x 11”)

• Practice Packet– If complete at least 80% and turn in by day of

final will get to participate in any curve added to final.

What to Study?

• Physics Skills– What is physics

• The study of mass and energy and their interactions

– Science vs. technology• Problem solving process vs. a product

– Scientific method, variables• Order of the steps• What is a hypothesis and its purpose• Control vs. experimental groups• Independent vs. dependent variables

– Math skills• Graph reading skills, calculating slope

– Liner, direct, indirect (inverse) relationships

• Using right triangle rules and trig functions• Significant figures• Scientific notation• Algebraic manipulation of equations

– Metric system• Know the common units of measure and prefixes

– gram, meter, second or hour, Newton, etc.– milli, centi, kilo, mega, etc.– Perform simple conversions

» i.e., meters to kilometers

kilograms to grams

hours to seconds

• Motion– Point of reference and frame of reference– Distance vs. displacement– Speed vs. velocity– Motion word problems

• i.e, speed, distance, velocity, displacement and time of travel

– Motion graphs• Position-time graph

– Meaning of slope

• Velocity time graph– Meaning of slope and area under line

• Acceleration– Recognize when something accelerates– Solve acceleration problems

• i.e, acceleration, final velocity, initial velocity, displacement, and time of travel

– Acceleration-time graphs• Meaning of area under the line

• Free fall– Know the value of g– Solve free fall word problems

• i.e, time of fall, distance fell, landing velocity, maximum height reached if tossed.

• Force– Newton’s Laws of Motion

• Name the laws by number• Solve force word problems

F = m•a a = F/m

– Contact vs. field forces• What is gravity or a push?

– Friction• Types of friction• Affects of friction• Solve friction word problems

– Hooke’s Law

• Vector addition– Difference between vectors and scalars– Graphical method of vector addition– Analytical method of vector addition– Crossing river and plane navigation problems

• Projectile Motion– Describe the trajectory of a projectile– X and Y components of velocity and

displacement– When is Vy max or minimum– Independence of X and Y– Solve projectile word problems
