In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field.
These include differential equations, manifolds, Lie groups, and ergodic theory. [4] This article gives a summary of the most important of these. This article lists equations from Newtonian mechanics , see analytical mechanics for the more general formulation of classical mechanics (which includes Lagrangian and Hamiltonian mechanics ).
Formula E is the highest class of competition for single-seat, electrically powered racing cars, which held its inaugural season in 2014–15.Conceived in 2012, the championship was intended by the FIA to serve as an R&D platform for the electric vehicle and promote interest in EVs and sustainability.

The Formula 4 South East Asia Championship is a formula racing series run to FIA Formula 4 regulations. The inaugural season was held over 2016 and 2017 . The COVID-19 Pandemic put a momentary stop to the championship in 2020, but in 2023, the championship was revived under a new promoter.
Power is the rate with respect to time at which work is done; it is the time derivative of work: =, where P is power, W is work, and t is time.. We will now show that the mechanical power generated by a force F on a body moving at the velocity v can be expressed as the product: = =
In fluid dynamics, the drag equation is a formula used to calculate the force of drag experienced by an object due to movement through a fully enclosing fluid. The equation is: F d = 1 2 ρ u 2 c d A {\displaystyle F_{\rm {d}}\,=\,{\tfrac {1}{2}}\,\rho \,u^{2}\,c_{\rm {d}}\,A} where
Settling velocity W s of a sand grain (diameter d, density 2650 kg/m 3) in water at 20 °C, computed with the formula of Soulsby (1997). When the buoyancy effects are taken into account, an object falling through a fluid under its own weight can reach a terminal velocity (settling velocity) if the net force acting on the object becomes zero.
F 4. force by object on support (downward) Forces F 1 and F 2 are equal, due to Newton's third law; the same is true for forces F 3 and F 4. Forces F 1 and F 3 are equal if and only if the object is in equilibrium, and no other forces are applied. (This has nothing to do with Newton's third law.)
