## Uniformly accelerated linear motion

This tool calculates the acceleration of a uniformly accelerated linear motion object (i.e. constant acceleration) from two speeds (v_1 and v_2) measured at two different instants (t_1 and t_2).

a: Acceleration (constant) of the object
v_1: speed at an instant t_1
v_2: speed at an instant t_2

In a uniformly accelerated linear motion, the rate of change in velocity is constant over time. The equation that connects these quantities is,

a = (v_2 - v_1)/(t_2 - t_1) = (\Deltav)/(\Deltat)

a > 0

## Uniformly slowed linear motion

In that case, the speed of the moving object is slowing down over time with a negative rate of variation: deceleration instead of acceleration in the previous case. So we have,

a = (v_2 - v_1)/(t_2 - t_1) = (\Deltav)/(\Deltat)

a < 0
