FINAL REVIEW TOPICS

3" x 5" FORMULA CARD allowed.

Scientific Notation (n.nn x 10^nn)

Fundamental v. Derived Quantities

Motion

Speed vs. Velocity

Distance vs. Displacement

Vector vs. Scalar Quantities

Vectors (two vector addition, three vector addition), angle measured from 0 deg, DUE NORTH) Use pythagorean thereom, SOHCAHTOA, Law of Sines, & Law of Cosines

Acceleration = Δ v/time

Free Fall (d=1/2at^2)

Kinematics (4 kinematics equations)

Position v. Time graphs:  Slope =?????

Velocity  v. Time graphs:  Slope =????  Area Under line=?????

Ball & Hoop ==> Projectile motion (motion in two dimensions:  Horizontal & Vertical motion [freefall])

Projectile Motion (Launch Angle & Launch Velocity==>Range?  Apogee?  Hang time?)

Determining Acceleration Due to Gravity (given data set, can you determine acceleration due to gravity for another planet???)

Galileo Reading/ Ramp Lab:  Free fall

Dynamics ==> 

Newton's three laws:

1) Law of Inertia

2) F=ma

3) action ==> equal opposite reaction

Random stuff:  Crazy pseudo-science ==> Use physics concepts from semester one to DEBUNK crazy pseudo-science

Circular Motion:  Centripetal Force?  Centrifugal force? Velocity?

Collisions:  LAW OF CONSERVATION OF MOMENTUM / Conservation of Kinetic Energy

Types of Collisions:  partially elastic, inelastic, elastic

Kinetic Energy:  Energy of Motion

Potential Energy:  Stored energy, energy of position (Gravitational Potential Energy)

Work

Total mechanical Energy (Sum of Kinetic and Potential energy [Cliff-diver] )

Tycho Brahe (made celestial observations, trying to prove planet circled Sun in perfect circles)

Keppler, upon death of Brahe, took Brahe's observations, and developed three laws of planetary motion:

1)planet travel in ELLIPTICAL ORBITS, with one focus at the Sun)

2)  square of T (period) is proportional to the cube of the semi-major axis R (mean distance from the sun) T^2/R^3 = k, k is the same for ALL PLANETS

3)  A line drawn from a planet to the Sun will sweep out equal areas in equal time intervals.

Newton's Law of UNIVERSAL Gravitation.  Objects with mass are attracted to each other.

(G*m1*m2)/r^2, r= distance between centers of gravity for each mass.

increase mass, force of gravity increases, increase r, force gravity decreases to the inverse square of distance.   F grav ~ 1/r^2 ( Law of Inverse Square)

Satellite Motion:  Centripetal force (gravity between sat. and the object it's revolving around)  Increase gravity, velocity of sat would increase

Rotational Motion:  Law of Conservation of Angular Momentum (Figure Skater in Death Spiral)

Free Body Diagrams:  Label ALL forces acting upon a body.
