The equations of motion are a set of mathematical equations that describe the motion of an object in terms of its position, velocity, and acceleration. There are three equations of motion, which are as follows:
- The first equation of motion, also known as the velocity equation, relates an object’s final velocity (v) to its initial velocity (u), acceleration (a), and the time (t) over which it accelerates or decelerates. The equation is:v = u + at
- The second equation of motion, also known as the displacement equation, relates an object’s displacement (s) to its initial velocity (u), final velocity (v), acceleration (a), and the time (t) over which it accelerates or decelerates. The equation is:s = ut + 0.5at^2
- The third equation of motion, also known as the velocity-time equation, relates an object’s final velocity (v) to its initial velocity (u), acceleration (a), and the distance (s) over which it accelerates or decelerates. The equation is:v^2 = u^2 + 2as
These equations can be used to solve a wide range of problems involving the motion of objects, from simple free fall to complex systems of interacting bodies.
