| Question | Answer |
|---|---|
| F~(m1 x m2)/d squared | Newtons Law of Gravition |
| An object will continue doing the same thing unless acted upon by another force | 1st Law of Motion |
| Accerlation = force divided by mass a=f/m | 2nd Law of Motion |
| Every Action has an equal and opposite reaction | 3rd Law of Motion |
| Object that is projected by some means and continues in motion by it's own interia | Projectile Motion |
| A projectile moving fast enough to continuously orbit earth | Satellite |
| Mercury, Venus, Earth, Mars | Inner Planets |
| Jupiter, Saturn, Uranus, Neptune, Pluto | Outer Planets |
| A giant cometary sphere completely surrounding the solar system | Oort Cloud |
| What is an electrical force? | Positive and Negative Paricles attracting each other |
| What is the conservation of charge? | Charge is never created or destroyed |
| What is an Ion? | Charged Atom |
| F=K q1 q2/d squared | Coloumbs Law |
| 1 C equals | 6.25 billion billion electrons |
| Ends of an electrical conductor are at different electric potentials, and charges flow from higher to lower potential. | Potential difference |
| Ampheres | Rate of electric flow of 1 coloumb per second |
| Ohms | Electrical Resistance measurement |
| Current= voltage/resistance OR Ampheres = volts/ohms OR I=V/R | Ohns Law |
| Resistors | Regulate the current inside electrical devices, in ohms |
| Power | The rate at which work is done |
| Potential Energy (PE) | stored energy with the potential to do work |
