Relative error is defined as the ratio of the absolute error of the measurement to the actual measurement. Using this method we can determine the magnitude of the absolute error in terms of the actual size of the measurement. If the true measurement of the object is not known, then the relative error can be found using the measured value. Relative error gives an indication of how good a measurement is relative to the size of the object being measured.

If x is the actual value of a quantity, x_{0} is the measured value of the quantity and Δx is the absolute error, then the relative error can be measured using the below formula.

Relative error = (x_{0}-x)/x = (Δx)/x

An important note that relative errors are dimensionless. When writing relative errors it is usual to multiply the fractional error by 100 and express it as a percentage.

Joule✅
As Work = Force × Displacement
W = Nm/s^2 × m
W = Nm^2/s^2
W = Joule

Gravitation is the force of attraction between any two bodies. All the objects in the universe attract each other with a certain amount of force, but in most of the cases, the force is too weak to be observed due to the very large distance of separation. This force of attraction was first observed by Sir Isaac Newton and was presented as Newton’s law of gravitation in the year 1680.

The SI unit of pressure is Pascal (represented as Pa) which is equal to one newton per square metre (N/m^{-2} or kg m^{-1}s^{-2}).

The CGS unit of pressure is barye (Ba), equal to 1 dyn·cm−2, or 0.1 Pa.

A Pseudo force (also called as fictitious force, inertial force or d’Alembert force) is an apparent force that acts on all masses whose motion is described using a non-inertial frame of reference frame, such as rotating reference frame.

Pseudo force comes in effect when the frame of reference has started acceleration compared to a non-accelerating frame.
