IBSEHS Newton's Laws of Motion & Conversion of Angular Momentum & Bernoulli's Principle

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

1. The direction of spin determines the force on the object

2. The force is perpendicular to the speed & direction of the object
