Force

The equation for force according to Newton's second law of motion is $F = ma$, where $F$ is the force, $m$ is the mass, and $a$ is the acceleration.

Acceleration ($a$) is defined as the change in velocity ($v_f - v_i$) divided by the time interval ($t$), expressed as $a = \frac{v_f - v_i}{t}$.

The relationship between force and change in momentum is given by the equation $F = \frac{\Delta p}{t}$, where $F$ is the force, $\Delta p$ is the change in momentum, and $t$ is the time interval.
