A = nucleon number (atomic mass) a = acceleration.
What is A and V in physics?
a = acceleration ∆v = change in velocity ∆t = elapsed time The definition of acceleration.
What is U in physics class 9?
u is initial velocity. v is the final velocity. a is acceleration. t is the time period.
What is current formula?
The current formula is given as I = V/R. The SI unit of current is Ampere (Amp).
What does V 2f mean in physics?
Final velocity (v) squared equals initial velocity (u) squared plus two times acceleration (a) times displacement (s).
What is the R in physics?
r = radius. R = resistance. R = molar gas constant.
What is the difference between M and M in physics?
The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. Mass is the measure of the amount of matter in a body. Mass is denoted using m or M. Weight is mass multiplied by the acceleration of gravity (g).
What does P mean in physics?
Momentum is a measurement of mass in motion: how much mass is in how much motion. It is usually given the symbol p. The useful thing about momentum is its relationship to force.
What is this symbol μ?
Micro (Greek letter μ (U+03BC) or the legacy symbol µ (U+00B5)) is a unit prefix in the metric system denoting a factor of 10−6 (one millionth). Confirmed in 1960, the prefix comes from the Greek μικρός (mikrós), meaning “small”. The symbol for the prefix is the Greek letter μ (mu).
What is the symbol of force?
A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newton (N). Force is represented by the symbol F (formerly P).
