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.

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
