Physics equations of motion are a basic concept that we all might have studied in middle school. It is important to understand what it means and what we do with it from a young age so that it becomes easier to understand complicated concepts correlated with it in the future.
We use this concept in various ways, for example, while playing sports or driving a car, even without the knowledge of actually using it. This article will discuss Physics equations of motion in detail while having a good look at other similar concepts.
In kinematics, equations of motion are defined as the basic motion concept of an object, including velocity, position, and acceleration, which are performed at varying intervals of time. These three motion equations govern an object’s motion in 1, 2, and 3 dimensions.
Simply put, the Physics equations of motion are the set of equations capable of describing a physical system’s behavior in terms of its motion as a function of time. Hence, the equation of motion is the relation between these quantities.
Uniform acceleration in equations of motion includes three different equations. These are called the laws of constant acceleration. Therefore, we can utilize these equations for deriving components such as velocity (initial and final), acceleration (a), displacement (s), and time (t).
Hence, these are applied only where there is a constant acceleration and the motion is in a straight line. The following are the three equations:
The first equation of motion: v = u + at
Second equation of motion: s = ut + 12 at2
Third equation of motion: v2 = u2 + 2as
where,
s = displacement
u = initial velocity
v = final velocity
a = acceleration

t = time of motion
We can call these quantities SUVAT. It stands for displacement, initial velocity, final velocity, acceleration, and time of motion.
