Acceleration is how fast something speeds up or slows down. Use this formula: Acceleration = (Final Speed - Starting Speed) ÷ Time. Example: If a car goes from 0 to 60 mph in 5 seconds: (60 - 0) ÷ 5 = 12 mph per second.
To calculate acceleration, use the formula a = (v₂ - v₁) / t, where v₂ is the final velocity, v₁ is the initial velocity, and t is the time taken. The result shows how quickly velocity changes over time. Acceleration is measured in meters per second squared (m/s²).
