| 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?
I
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.
