Our free Acceleration Calculator helps you quickly find the rate of change of velocity of an object. Just enter initial velocity, final velocity, and time to get instant results. This tool is useful for students, teachers, and professionals studying motion and kinematics.

How to Use the Acceleration Calculator

  • Step 1: Enter the initial velocity of the object.
  • Step 2: Enter the final velocity.
  • Step 3: Enter the time interval in seconds.
  • Step 4: Click on "Calculate" to get the acceleration value instantly.

The calculator also supports different units, making it easier to solve both academic and real-world physics problems.

Acceleration Formula

The formula used in our acceleration calculator is:

Acceleration (a) = (Final Velocity – Initial Velocity) ÷ Time

If the result is positive, the object is speeding up. If it is negative, the object is slowing down (deceleration).

Units of Acceleration

The most common unit used by our acceleration calculator is m/s² (meters per second squared). Other units include:

  • Kilometers per hour squared (km/h²)
  • Feet per second squared (ft/s²)
  • Centimeters per second squared (cm/s²)

Example Calculation

Question: A car accelerates from 10 m/s to 30 m/s in 5 seconds. Find its acceleration using the calculator.

Solution:

  • Initial velocity (u) = 10 m/s
  • Final velocity (v) = 30 m/s
  • Time (t) = 5 s

Using the formula: a = (v – u) ÷ t = (30 – 10) ÷ 5 = 20 ÷ 5 = 4 m/s²

The car’s acceleration is 4 m/s². The same result can be instantly verified with our online acceleration calculator.

Types of Acceleration

Our calculator works for basic linear acceleration, but here are some other types:

  • Tangential Acceleration: Change in tangential speed during circular motion. Calculate here.
  • Centripetal Acceleration: Inward acceleration in circular motion. Use calculator.
  • Angular Acceleration: Change in angular velocity in rotational motion. Find here.
  • Gravitational Acceleration: Acceleration due to Earth’s gravity (≈ 9.8 m/s²). Check with calculator.
