Basic Physics Formulas Concept Formula
Mass Formula This formula represents the relationship between force and mass. Here, F = force, m = mass, and a = acceleration. F = ma or m = F/m

What is a chemical formula in physics?

The chemical formula is a method of providing information about the chemical proportions of atoms that make a particular chemical compound or molecule by chemical elements numbers and symbols. Moreover, it simply specifies the simplest of molecules and chemical substances. …

What is a formula of a compound?

A chemical formula is an expression that shows the elements in a compound and the relative proportions of those elements. Molecular formulas do not indicate how the atoms are arranged in the molecule. The empirical formula tells the lowest whole-number ratio of elements in a compound.

What is the symbol for current?

The conventional symbol for current is I, which originates from the French phrase intensité du courant, (current intensity). Current intensity is often referred to simply as current. The I symbol was used by André-Marie Ampère, after whom the unit of electric current is named, in formulating Ampère’s force law (1820).

Which is the most important formula in physics?

1 Average Speed Formula: 2 Acceleration Formula: 3 Density Formula: 4 Newton’s Second Law: 5 Power Formula: 6 Weight Formula: 7 Pressure Formula: 8 Kinetic Energy formula: 9 Ohms Law Formula: 10 Frequency Formula:

Which is the correct formula for kinetic energy?

Kinetic Energy; energy of motion = 1/2 x mass x velocity². Gravitational potential energy; energy due to height of an object above the Earth=mass x gravity x height (g=10 m/s²). Conservation of energy for a falling body, energy at top (mgh) is equal to the energy at the bottom (1/2 mv²) and vice versa.

Which is the correct equation for thermal physics?

Thermal Physics 1 ∆A = 2αA0∆T 2 ∆V = 3αV0∆T 3 P = εσA(T4 − T04) 4 ∆U = Q + W

Which is the correct formula for efficiency in physics?

Power is the rate of work or energy transfer. Efficiency = (useful work or power output) / (total work or power input) x 100%. P=pgh density x gravity x height (depth in the water). The heat energy is joules required to change temperature of matter with no phase change.
