1. A surgical instrument, comprising:
an elongated channel configured to support a staple cartridge;
an anvil pivotably connected to the elongated channel;
a closure tube mechanically coupled to the anvil;
an electric motor; and
a control circuit electrically connected to the electric motor, wherein the control circuit is configured to:
determine a firing force of the surgical instrument during a firing motion of the surgical instrument;
determine a projected peak firing force based on the determined firing force;
determine, based on the projected peak firing force, whether to change the firing motion of the surgical instrument;
determine, in response to a determination to change the firing motion of the surgical instrument, a rate of at which the projected peak firing force is approaching a predetermined threshold firing force; and
change the firing motion of the surgical instrument to (i) a first firing motion in response to the rate being equal to a first rate and (ii) a second firing motion, different from the first firing motion, in response to the rate being equal to a second rate different from the first rate.
