Distance |
How far |
|
Displacement |
How far you were from the start |
|
Average Speed |
How fast you covet a certain distance |
|
Velocity |
How fast your position changes |
|
Acceleration |
How fast your speed changes |
|
1st Law |
Object at rest stays at rest same with motion |
|
2nd Law |
Acceleration depends on how big the unbalanced force is |
|
3rd Law |
Every action has an equal and opposite reaction |
|
Net Force |
Sum of all forces |
|
Equilibrium |
Forces are balanced (Sum of all forces is zero) |
|
Types of Forces |
Tension, Fg, Friction, Normal, Applied Force |
|
Circular Motion |
An object in uniform circular experiencing a change in direction, not speed. |
|
Centripetal |
Center Pointing |
|
Period (T) |
Complete one full revolution. |
|
Momentum |
Mass in motion and it is a vector so directions matter |
|
What do you need to change momentum |
Force and Time (Impulse). Longer time = less force. |
|
Momentum is always what? |
Conserved as long as there is no outside forces. |
|
Inelastic Collisions |
Objects stick together (final velocities are the same) |
|
Elastic Collisions |
Bounce off eachother |
|
Kinetic Energy |
Conserved in elastic Collisions only. |
|
Kinetic Energy 2 |
Energy of motion |
|
Energy |
Ability of potential to do work. |
|
Work |
Done when an object moves a distance |
|
Gravitational Potential Energy |
Energy stored in an objects height |
|
Conductors |
Loosely bound electrons (metals, water, humans) |
|
Insulators |
Tightly bound electrons |
|
Charging By Friction |
2 insulators that are rubbed together (insulator with greater attraction for electrons will steal from the other insulator leaving one + and the other -) |
|
Charging by Contact |
2 conductors. Charged conductor to a neutral and left with a charge opposite of the charge being held near it |
|
Charging by induction |
Hold a charge near a neutral conductor, ground the conductor, and it will be left with a charge opposite of the charge being held near it. |
|
Grounding |
Connect a charged conductor to the ground makes it neutral |
|
Electric Field |
Pointed away from a positive charge and towards a negative charge |
|
Voltage |
How much energy a charge gains or loses from one point to another |
