Eureka Videos name: _______________________ Eureka 1 - Inertia (http://tinyurl.com/nlps5uo) (1:22) Things “like” to keep on doing ________________________________________________________1. Physicists have a special word for “laziness”: ______________________. Example: Eureka 2 – Mass (http://tinyurl.com/nbrqynd) The more the ________________, the more the ________________. Example: Eureka 3 – Speed (http://tinyurl.com/neczmzh) Force varies with Mass and __________________________________________. Example: Eureka 4 – Acceleration p.I (http://tinyurl.com/pd6zqr9) Force = _____________________ X ________________________________ Example: Eureka 5 – Acceleration p.II (http://tinyurl.com/owj9ljx) Acceleration = ___________________ Example: Eureka 6 – Gravity (http://tinyurl.com/qhq34b5) All objects in the Universe __________________ all other objects to some extent. The Acceleration at which every object falls to the Earth is roughly ___________________________2. The Force of Gravity acting on the average apple3 is exactly ____________________________4. Example: Eureka 7 – Weight vs. Mass (http://tinyurl.com/noelr5a) In Physics, Kilograms measure your ________________, but your _________________ is always measured in Newtons. Wherever you go on the Universe, your mass ___________________________. Only your weight ____________________. Example: Eureka 8 – Work (http://tinyurl.com/qz8386n) Work = ______________ X _____________________________ 1 newton meter = 1 joule, or ____________ = _____________ Example: Eureka 9 – Kinetic Energy (http://tinyurl.com/ohpaz9l) Enegy = The _____________________________________________________. Both Work and Energy are _________________________________________________. The energy of movement = _________________________ energy. Example: Eureka 10 – Potential Energy (http://tinyurl.com/qz54u36) Potential energy is the energy of ___________________________. Example: Eureka Videos name: _______________________ Eureka 11 – Inclined Plane (http://tinyurl.com/npvulce) (0:42) The plank5 doesn't ____________________ the energy needed to do something, but it does help to use energy more ______________________. Example: Eureka 12 – Lever (http://tinyurl.com/q9xjauu) A fulcrum is a __________________________________. When you _________________ the distance you can _______________ the force. Example: Eureka 13 – Mechanical Advantage and Friction (http://tinyurl.com/qflnvlj) M.A.6 = _______________________________________ / ___________________________________ The Lever is a more efficient machine than the Inclined Plane because the Inclined Plane is ___________________________________________________. Example: Eureka 14 – Screw and Wheel (http://tinyurl.com/qawwjv6) There are only two basic machines: _______________________________ and __________________. A twisted Inclined Plane is called a _________________. The Circular Lever = ___________________________7 Example: Eureka 15 – The Pulley (http://tinyurl.com/p3rw9hb) A wheel that is used mainly for _____________________________________ is called a Pulley. To figure out the mechanical advantage of each system of pulleys, all you do is ___________________________________________________________supporting the weight. Example: NOTES 1. to ____________________ moving, or to ______________________________________ 2. _____________ m/s2 3. ______________ grams 4. ___________ 5 a.k.a. ____________________________________ 6. Mechanical Advantage has _________________________ 7. a.k.a. _______________ and _______________
