Answer:
Mathematically, the acceleration of a body at any time is the second derivative of the position:
[tex]a=\frac{d^2x}{dt^2}[/tex]
In addition, it can be obtained by deriving the speed of the body:
[tex]a=\frac{dv}{dt}[/tex]
Explanation:
In classical mechanics acceleration is defined as the variation of speed with respect to time:
[tex]a=\frac{dv}{dt}[/tex]
In Newtonian mechanics, for a body with constant mass, the acceleration of the body measured by an inertial observer is proportional to the force acting on it:
[tex]F=ma\\\\a=\frac{F}{m}[/tex]
