What Is Acceleration?

Acceleration is the rate at which an object's velocity changes over time. It is a vector quantity, having both magnitude and direction, and is measured in meters per second squared (m/s²). A positive value indicates speeding up in the chosen direction, while a negative value indicates slowing down or accelerating in the opposite direction.

Formulas

  • a = Δv / t = (v_f − váµ¢) / t - From change in velocity and time
  • a = F / m - From net force and mass (Newton's second law)

Units

  • váµ¢, v_f - Velocity (meters per second, m/s)
  • t - Time (seconds, s)
  • F - Force (newtons, N)
  • m - Mass (kilograms, kg)
  • a - Acceleration (meters per second squared, m/s²)
