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 |

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 |
Examples of Chemical Potential Energy | Batteiries, Fossil Fuels |
Example of Potential Energy | Bow and Arrow |
Example of Gravitational Potential Energy | Water in reservoir |
