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.
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.
A person's body can accelerate in three different ways:
The following methods can be used to calculate acceleration. They are as such
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.
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

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
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?
4. What is the best way to determine the magnitude of acceleration?
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.
