Newton's laws of motion

Newton's 1st Law

An object at rest will remain at rest unless acted upon by an external force, and an object in motion will remain in motion with the same speed and in the same direction unless acted upon by an external force. This law is often referred to as the law of inertia.

Newtons 2nd law

F=ma

Newtons 3rd law

For every action there is an equal/opposite reaction

Pitch

Related to the Frey of a sound wave

Young's modulus

measures a material's ability to withstand changes in length when compressed or stretched lengthwise. It's calculated by dividing the longitudinal stress by the strain.

Bulk modulus

material's ability to resist changes in volume when compressed from all sides.

Shear modulus

measures the amount of tangential force applied per unit area to the angular deformation in radians. It's calculated by dividing the shearing stress by the shearing strain

elastic modulus

general term for measuring a material's elasticity. It quantifies a material's resistance to non-permanent, or elastic, deformation

Scalar quantity

A physical quantity that has magnitude only, without direction, such as mass, temperature, or speed.

Bernoulli's principle

In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or potential energy.
