Question

First equation of motion does not contain the physical quantity,named.....​

Answer 1

Answer:

In physics, equations of motion are equations that describe the behavior of a physical system in terms of its motion as a function of time.[1] More specifically, the equations of motion describe the behaviour of a physical system as a set of mathematical functions in terms of dynamic variables. These variables are usually spatial coordinates and time, but may include momentum components. The most general choice are generalized coordinates which can be any convenient variables characteristic of the physical system.[2] The functions are defined in a Euclidean space in classical mechanics, but are replaced by curved spaces in relativity. If the dynamics of a system is known, the equations are the solutions for the differential equations describing the motion of the dynamics.

Answer 2

Answer:

Each equation of motion contains four physical quantities from which any one can be found out if all the rest three are known. The first equation of motion in the same way consists od v,u,a and t So, the physical quantity that is not used in the first equation of motion is displacement.
