Static variables are shared among all instances of a class, while non-static variables belong to individual instances.
Static variables are declared using the 'static' keyword, while non-static variables are not.
Static variables are initialized only once at the start of the program, while non-static variables are initialized each time an instance is created.
Static variables can be accessed using the class name, while no...

Gravity is a force that attracts objects with mass towards each other.
Gravity is a fundamental force of nature.
It is responsible for keeping planets in orbit around stars.
The strength of gravity depends on the mass and distance between objects.
Gravity is what gives weight to objects on Earth.
It was first described by Sir Isaac Newton in his law of universal gravitation.
Newton's laws of motion are three fundamental laws that describe the relationship between a body and the forces acting upon it.
First law: An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity, unless acted upon by an external force.
Second law: The acceleration of an object is directly proportional to the force applied to it and inversely proportional to its mass.
Thi...
The Bernoulli equation relates the pressure, velocity, and height of a fluid in motion.
Describes the conservation of energy in a fluid system
Used to calculate fluid flow in pipes and channels
Can be applied to both incompressible and compressible fluids
Example: Air flowing over an airplane wing creates lift due to differences in pressure
Example: Blood flow through arteries and veins can be modeled using Bernoulli's equa
