The Acceleration Calculator is a free online tool that takes the initial velocity, final velocity, and time to compute the acceleration of an object fast and easily. To get the acceleration in the blink of an eye, just enter the initial velocity (vi), final velocity (vf), and time (t) into the calculator's designated input areas and click the calculate button.
What is Acceleration?
The rate at which the velocity of a moving body changes over time is called Acceleration. A body is said to be accelerated when it is moving and abruptly alters its velocity.
Acceleration should not just be considered in terms of speed, but also terms of velocity. Speed and velocity are two separate notions, as we all know. Velocity is a vector, while speed is a scalar number.
What is the Process of Acceleration?
A person's body can accelerate in three different ways:
- By altering the speed
- As either a result of the shift in direction.
- By altering both the speed and the direction of travel.
- A body is said to be accelerating in any of the situations above.
Methods to Calculate Acceleration?
The following methods can be used to calculate acceleration. They are as such
- Using Time Intervals and Velocities: You'll need to know the change in velocities in a specific time interval to compute acceleration using this approach. If Vi and Vf are the initial and final velocities of a body during a certain time period of 'tf' and 'ti' seconds, therefore the acceleration 'a' of a body for this kind of time interval is (Vf- Vi)/(tf- ti). In other terms, a = Δv ÷ Δt is the acceleration. The unit of acceleration is m/s2 according to this equation.
- Using Force and Mass Values: A body undergoes acceleration as a result of the force exerted on it, according to Newton's law. F = m x a is the relationship between the force F acting on a body of mass 'm' and the resulting acceleration 'a' produced in it. As a result, the acceleration 'a' = F / m
- The Use of a Velocity Vector: Acceleration is obtained by differentiating the velocity vector with respect to time. The acceleration a may be computed as follows, assuming the displacement vector 's' and the velocity vector is 'v. Average Acceleration = ∆v / ∆t =( vf - vi) / (tf - ti)
Step by Step Procedure to Calculate Acceleration
The easy procedures for determining acceleration are shown below. If you follow these guidelines, you'll be able to acquire the results you need in less time.
- Let's start with the initial velocity, then the final velocity, and time.
- Calculate the difference between the final and initial velocity.
- To get the acceleration value, divide the acquired difference number by the given time.
Examples on Finding Acceleration
Question 1: A moving object started at a speed of 4 m/s and increased to a speed of 10 m/s in 4 seconds. Determine the average acceleration?
Given: vi=4 m/s, vf=10 m/s , t= 4 sec
Average acceleration is given as a=vf−vi / t
a=10−4 / 4 = 1.5 m/s2
Question 2: A moving object has a velocity of 2 m/s and a 5 m/s2 acceleration. After 5 seconds, determine the velocity?
Given: vi= 2 m/s, vf= ? , t= 5 sec, a = 5 m/s2
Average acceleration is given as a = vf−vi / t
Rearranging this we have vf = vi+at
vf = 2+5×5 = 27 m/s

Acceleration Related Terms
Positive Acceleration: When the ultimate velocity of a body exceeds the starting velocity, it is said to be experiencing positive acceleration.
Negative Acceleration: When a body's ultimate velocity is less than its beginning velocity, it is said to be experiencing negative acceleration. It's commonly referred to as deceleration, although experts believe the correct phrase is negative acceleration.
Centripetal Acceleration: When a body moves in a circular motion, it experiences centripetal acceleration. When determining centripetal acceleration, the idea of circular velocity must be taken into account.
Linear Acceleration: The acceleration a body experiences as it moves in a straight line without changing direction.
Instantaneous Acceleration: The acceleration that a body experiences at any given time or during an infinitesimally short time interval is known as instantaneous acceleration.
Gravitational Acceleration: The acceleration that every freely falling body experiences on Earth is symbolised by the letter 'g.' This is due to Earth's gravitational pull. The gravitational acceleration is 9.8 m/s2
Real Life Examples of Acceleration
- A body that falls freely, such as a stone or an apple, from a specific height.
- An automobile speeding up as it tries to pass another vehicle.
- A swimmer diving into a pool.
- A golf ball is a piece of equipment that is used to hit a golf ball.
FAQs on Acceleration Calculator
1. Is acceleration a vector?
Acceleration is a vector quantity because it has both magnitude and direction. The magnitude indicates how rapidly the item is accelerating, while the direction indicates whether the acceleration is travelling in the same direction as the object or in the opposite direction. This is the difference between acceleration and deceleration.
2. Is it possible for acceleration to be negative?
Yes, deceleration may occur when acceleration is negative. Two objects with the same acceleration but different directions will accelerate by the same amount in opposite directions.
3. What's the easiest way to find the average acceleration?
- Calculate the change in velocity over a specified period of time.
- Calculate the change in time for the relevant time period.
- Multiply the difference in velocity by the difference in time.
- The average acceleration for that time period is the outcome.
4. What is the best way to determine the magnitude of acceleration?
- Convert the force's magnitude into Newtons.
- Convert the object's mass to kilogrammes.
- To calculate the acceleration in m/s2, multiply both numbers together.
5. With velocity and time, how can you calculate gravity's acceleration?
The g = - 9.81 m/s2 is the gravitational acceleration near the earth. To get the speed (or velocity) of anything after a specific length of time, multiply the acceleration of gravity by the time after it was released. As a result, velocity = -9.81 m/s2 x time (or V = gt) is calculated.
