Distance – Displacement=CHANGE in position • Velocity v. Speed x v t Ch2 Specifics • Acceleration v v f vi a t t Ch2 Specifics • Free Fall m a g 9.805 2 s Fizzoids use 10 m s 2 General List of Stuff: • 2-D Motion (Ch3) – Projectile Stuff – TWO individual Probs • H&V – Vectors vs Scalars Ch3 Specifics • • Scalar v. Vector Scalar has ONLY size (magnitude if you like big fancy woids…) – Distance = 5 m – Mass = 100 kg – Speed = 60 MPH Ch3 Specifics • • Scalar v. Vector Vector has BOTH size and DIRECTION – Displacement = 5 m North – Weight = 1000 N Downward – Velocity = 60 MPH South Ch3 Specifics • Vector Addition – Add graphically / algebraically • Head-to-Tail – Boy Scout hike 3km North, then 4 km East • Find d and d 4 km d=7 km & d = 5 km 53o E of N 3 km 5 km Ch3 Specifics • Vector Addition with non-right triangles – Use LOC 4 km >5 km c a b 2ab cos 2 2 3 km 2 Ch3 Specifics • Projectiles & Relative Motion – Range Equation v sin 2 R g 2 i Ch3 Specifics • Projectiles & Relative Motion – Relative Motion General List of Stuff: • Newton’s Laws – Ch4 – 1. I – 2. Biggee – 3. F = -F • F ma Friction & motion caused by F Ch4 Specifics • Force – Push or pull – Measured in Newtons 1kg 1m 1N 2 1s Ch4 Specifics • Free Body Diagrams – Sketch with all forces acting on body Ch4 Specifics • Weight of an object – Since F=ma, Fg=mg – Fg is WEIGHT • Normal Force – Force perpendicular to surface – Force surface “fights back” with due to NL3 Ch4 Specifics • Friction – Force that resists motion when two surfaces are in contact moving relative to each other. Ch4 Specifics • Friction – Kinetic Friction is friction while IN MOTION – Static friction is friction while NOT IN MOTION F f N MAX s General List of Stuff: • Rotation & Gravitation Ch5 – Kepler’s Laws T 4 K 3 R GM s 2 2 General List of Stuff: • Rotation & Gravitation m1m2 Fg G 2 r Fc mac mv Fc r 2 Ch5 Specifics • Circular Motion & Gravitation – Radian : Angle subtending an arc of length r. – 2 radians = 360o l r Ch5 Specifics • Circular Motion & Gravitation – Angular velocity: t Ch5 Specifics • Circular Motion & Gravitation – Angular acceleration: t Ch5 Specifics • Circular Motion & Gravitation – Linear to angular equations v f vi at f i t Ch5 Specifics • Circular Motion & Gravitation – Linear to angular equations 2ad v v 2 f 2 i 2 2 f 2 i Ch5 Specifics • Circular Motion & Gravitation – Centripetal Acceleration 2 v ac r Ch5 Specifics • Circular Motion & Gravitation – Centripetal Force 2 v Fc m r Ch5 Specifics • Kepler v. Newton – Kepler’s 3rd Law Orbital Period 2 T K 3 R Orbital Radius T 4 KCh5 Specifics 3 R GM s 2 2 • Kepler v. Newton – Newton’s 4th Law 2 M 1M 2 v Fg Fc G M 1 2 R r General List of Stuff: W Fd cos W Fd (mg )h PE • Work & Energy Ch6 1 2 W Fd mad mv KE 2 General List of Stuff: • Work & Energy – Springs & Pendulae – Power 1 PE kx 2 s 2 W E P t t mgh Fv t Ch6 Specifics • Work – F and d MUST be in same direction Ch6 Specifics • Work & Energy – Essentially the same thing • Work CAUSES a CHANGE in E • Both are SCALARS W E Ch6 Specifics • Work Energy Theorem – Work & Energy must be CONSERVED within a closed system Wi Ei W f E f General List of Stuff: • Momentum (Ch7) – Impulse = P – Conservation of P is • Consequence of NL3 Impulse Change in P F ma v F m t Ft mv Ch7 Specifics • Momentum – – Product of mass and velocity Is a vector MV Ch7 Specifics • Momentum is Conserved – Immediately before and immediately after collisions. Pi Pf Ch7 Specifics • Two types of collisions – Elastic: BOTH P and KE are conserved • General hint: Start and end with same number of unhampered objects – Inelastic: ONLY P is conserved • General Hint: Start with 2 objects end with 1.
