Our free acceleration calculator helps you solve physics problems involving motion. Calculate acceleration from velocity changes, find final or initial velocity, determine time duration, or compute distance traveled. Perfect for physics students, engineers, and anyone working with motion equations.
Acceleration is the rate of change of velocity with respect to time. It measures how quickly an object speeds up, slows down, or changes direction. Acceleration is a vector quantity with both magnitude and direction. Positive acceleration means speeding up in the direction of motion, while negative acceleration (deceleration) means slowing down.
Acceleration Formula
a = (v - u) / t where v=final velocity, u=initial velocity, t=timeCalculate any kinematic variable: acceleration, final velocity, initial velocity, time, or distance.
Support for m/s², ft/s², km/h/s, and g-force with automatic conversions between all units.
Uses standard physics formulas: v = u + at, s = ut + ½at², and a = (v-u)/t.
Compare your results to real-world accelerations like gravity, car braking, or rocket launches.
Solve kinematics problems for homework, exams, or lab experiments.

Design systems with specific acceleration requirements or safety limits.
On Earth, the acceleration due to gravity (g) is approximately 9.81 m/s² or 32.2 ft/s². This means a freely falling object increases its velocity by 9.81 m/s every second. The value varies slightly by location and altitude.
