## List of elementary physics formulae

topic, reduce to a number of idealized special cases. 3. Formulae which frequently appear in **physics** literature, in a small addition some perhaps less common formulae. 4. Level of study is typically that of advanced school/ introductory degree level **Physics** , and beyond. 5. For generality

## Parity (physics)

In **physics** , a parity transformation (also called parity inversion ) is the flip in the sign of one spatial coordinate . In three dimensions, it is also commonly described by the simultaneous flip in the sign of all three spatial coordinates: A 3×3 matrix representation of P would

## Elasticity (physics)

In **physics** , elasticity (or stretchiness ) is the physical property of a material that returns to its original shape after the stress (e.g. external forces ) that made it deform or distort is removed. The relative amount of deformation is called the strain . The elastic regime is ]].

## Scalar (physics)

In **physics** , a scalar is a simple physical quantity that is not changed by coordinate system rotations or translations (in Newtonian mechanics), or by Lorentz transformations or space-time translations (in relativity). This is in contrast to a vector . A related concept is a pseudoscalar

## Jerk (physics)

In **physics** , jerk , also known as jolt (especially in British English ), surge and lurch , is the rate of change of acceleration ; that is, the derivative of acceleration with respect to time, the second derivative of velocity , or the third derivative of position . Jerk is defined by
