The acceleration, $a$, of an object is defined as
$$
a=\frac{\mathrm{d} v}{\mathrm{~d} t}
$$ where $v$ is the velocity of the object at time $t$. Given that when $t=0, v=u$, and the acceleration, $a$, is constant, show that $v=u+a t$.

Key Concepts

Differentiation

Differentiation is a process in calculus used to determine the rate at which a function is changing at any given point. In kinematics, the derivative of velocity with respect to time defines acceleration, providing a mathematical model for how an object's speed changes over time.

Integration

Integration is the inverse process of differentiation and enables us to recover a function when its rate of change is known. When the acceleration, regarded as the derivative of velocity, is integrated with respect to time, it yields the velocity function, illustrating how integration can be used to reconstruct motion equations.

Initial Conditions

When solving differential equations by integration, an arbitrary constant appears, reflecting the general family of solutions. Initial conditions, such as the initial velocity at time zero, are used to determine the specific value of this constant, ensuring the mathematical model accurately describes the physical motion.

Uniform (Constant) Acceleration

Uniform or constant acceleration implies that the rate of change of velocity does not vary with time. This constant nature significantly simplifies the integration process, resulting in a linear relationship between velocity and time, which is a fundamental result in the study of motion.
