Newton’s 1st Law; Law of Inertia
An object at rest stays at rest until acted upon by an external force
An object in motion stays in motion until acted upon by an external force
Newton’s 2nd Law; Law of Acceleration
Force = mass * acceleration
F = m * a
Newton’s 3rd Law; Law of Reaction
For every action, there is an equal and opposite reaction
Angular Momentum
A measurement of mass in motion (rotation) around an axis
Moment of Inertia
I=mr²
Inertia = mass * radius²
Angular Velocity
a measurement of how fast an object rotates around an axis
Equation of Angular Momentum
angular momentum = moment of inertia * angular velocity
L = I * w
Bernoulli’s Principle
The speed of a fluid (air) determines the amount of pressure that fluid can exert
Faster fluid has
lower air pressure
Slower fluid has
higher air pressure
Force pushes from
higher pressure to lower pressure
Magnus effect
The force generated by a spinning object moving through a fluid
The direction of spin determines the force on the object
The force is perpendicular to the speed & direction of the object
