Re: Formula list Physics
Oh you are preparing for the examination that’s good. ok here I am providing you the list of all formulas of Physics. Formulas of Physics Voltage (V) V = IR I = Current R = Resistance Power (P) P = I V V = Voltage Power (P) P = V2R R = ResistanceWatts (W) Power (P) P = I2 R I = Current Watts(W) Pressure- Pressure is defined as force per unit area: Pressure (P) = Force (F)/Area (A) Density Density is the mass contained in a body per unit volume. The formula for density is: Density (D) = Mass(M)/Volume (V) Angular Momentum- Angular momentum is an analogous quantity to linear momentum in which the body is undergoing rotational motion. The formula for angular momentum (J) is given by: J = r x p where J denotes angular momentum, r is radius vector and p is linear momentum. Torque Torque can be defined as moment of force. τ = r x F Circular Motion The formulas for circular motion of an object of mass 'm' moving in a circle of radius 'r' at a tangential velocity 'v' are as follows: Centripetal force (F) = mv2/r Centripetal Acceleration (a) = v2/r Power- Power is, work done per unit time. The formula for power is given as Power (P) = V2/R =I2R where P=power, W = Work, t = time. |
