The basic formulas depend on what you know:

- Average acceleration: a = (v_f − v_i) / (t_f − t_i) (units m/s²).
- Instantaneous acceleration: a = dv/dt (the time derivative of velocity).
- From kinematics (constant acceleration): a = (v_f² − v_i²) / (2Δx).
- From forces (Newton’s 2nd law): a = F_net / m.

Remember acceleration is a vector (direction matters); a negative value means the velocity is changing in the direction opposite your chosen positive axis.
