Acceleration Calculator
Calculate acceleration and distance from initial velocity, final velocity, and time.
Acceleration is the rate of change of velocity over time, measured in meters per second squared (m/s²). It is a key concept in Newton's laws of motion and applies to everything from vehicles to roller coasters to spacecraft.
The formula is: a = (v_f - v_i) / t, where v_f is final velocity, v_i is initial velocity, and t is time. The distance covered during uniform acceleration is: d = v_i * t + 0.5 * a * t².
Positive acceleration means speeding up, negative acceleration (deceleration) means slowing down. Earth's gravity provides a constant acceleration of 9.81 m/s². A sports car accelerating from 0 to 100 km/h in 5 seconds experiences about 5.56 m/s² or 0.57 g.
