The rate of change in velocity with respect to time. According to Newton's second law of motion, acceleration is equal to the force, divided by mass  (A=F/M).

Accelerator pumps are found in cars equipped with carburetors. When you accelerate, the accelerator pump delivers extra fuel through the accelerator pump circuit to allow the engine to deliver more po [..]
