Newtons Laws
Newtons First Law Of Motion
-Objects in motion remain in motion unless acted on upon a force. (this means that things don't just unexpectedly change direction)
Inertia
The measure of how much force it takes to make something stop doing what it's doing.
Newtons Second Law Of Motion
Force = mass x acceleration
Weight
The Force of gravity on an object (measured in newtons).
Image
Newtons Third Law Of Motion
-For every action there is an equal and opposite reaction
Freebody Diagrams
An easy way to visualize forces in a snapshot of time.
Freebody Example
Equilibrium
The state where all forces are balanced. (all the arrows on the freebody diagram are the same length)
Example
Unbalanced Forces
If something is accelerating the forces are unbalanced (the arrows opposite each-other are different lengths)
Example
Balanced Forces
All the arrows on the freebody diagram are the same length
Example
Friction and Drag/Air Resistance
Friction
Friction is the force that sticks anything that touches something else to that thing. Different surfaces have different levels of stick and therefor different friction coefficients.
Example/Equations
Static Friction
Static friction is the force needed to "de-stick" an object and get it moving.
Picture
Kinetic Friction
Kinetic friction is the force needed to keep an object from sticking to the ground while its moving and keep it moving.
Coefficient of Friction
How slippery the surface and the sliding thing are on the surface. This can be measured from 0 to 1.
1 being the hardest to slide and 0 being the easiest to slide.
Drag/Air Resistance
The force it takes to move the fluid your in as you move through it.
Example/Equation
Air Pressure
How hard the molecules of air are pressing on each-other or the thing they are inside.
Measured in newtons/meter squared (a pascal)
Drag
The force it takes for something to move through a fluid
Image
Air resistance
Drag but specifically in air.
Image
Terminal Velocity
The maximum speed you can go in a specific fluid while freely falling because the drag force is stopping you from accelerating further.
Miscellaneous
(Forces and whatnot)
Mass
The amount of matter in a certain object that remains the same no matter the gravity or other forces applied to it.
Image
Normal Force
The amount something pushes back against stuff siting on top of it.
Accelleration
Change in velocity over time
Newton
The amount of force it takes to accelerate 1 kilogram 1 meter per second per second.
