• Physics Skills (10%)– 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 (15%)– Point of reference and frame

of reference– Distance vs. displacement– Speed vs. velocity– Apply the principles of constant motion to explain situations

and make predictions– 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 (15%)– Recognize when something accelerates– Apply the principles of accelerated motion to

explain situations and make predictions– 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 (15%)– Know the value of g– Apply the principles of free fall

acceration to explain situations and make predictions

– Solve free fall word problems• i.e, time of fall, distance fell, landing velocity,

maximum height reached if tossed.

• Vector Addition (15%)– Difference between vectors and scalars– Graphical method of vector addition– Analytical method of vector addition– Crossing river and plane navigation problems– Add multiple vectors (e.g., forces) acting on a

single object– Apply the principles of vector addition to

explain situations and make predictions

• Projectile Motion (15%)– Describe the trajectory of a projectile– X and Y components of velocity and displacement

– When is Vy max or minimum

– Predict affects of angle of launch on range (dx) and height obtained (dy) for the projectile

– Independence of X and Y– Solve projectile word problems– Apply the principles of projectile motion to explain

situations and make predictions

• Force (15%)– Define what a force is– Recognize when an unbalanced force is

present and what affect it will have on an object

– Newton’s Laws of Motion• Apply the laws to explain situations and make

predictions• Name the laws by number• Solve force word problems

F = m•a a = F/m

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