For an object with unchanging mass, force equals mass times acceleration. This is abbreviated as f = ma. Force is a push/pull on an object resulting from interactions with another object. Having a magnitude and a direction makes force a vector quantity.

The formula for measuring potential difference is V=W/Q and this formula is known as Ohm's law. In this equation, V is equal to the potential difference, W is the energy transferred or work done and Q is the amount of the charge. Potential difference can also be measured using the formula V=IR, wher

The formula for calculating total water potential is matric or capillary potential + solute or osmotic potential + pressure potential or turgor pressure + gravitational potential. Water potential is a physical property that predicts the direction of water's flow, based on conditions such as pressure

The equation for calculating capacity is the same as calculating volume, so the equation for the capacity of a cube, for example, is the measurement of one of the sides cubed. Volume is the measurement of the total capacity of a container or object, describing its overall size.

www.reference.com/science/formula-calculating-density-c2c03cef7a604dfb

The formula for calculating density is mass divided by volume (density = mass/volume). Density is a measure of how much mass an object has per a given volume. Volume refers to the amount of three-dimensional space occupied by an object.
