In fact, almost every observable effect of motion comes from acceleration due to the influence of forces. Doubtless, everyone is familiar with the feeling of acceleration like when you press the gas pedal and are pushed back into your seat. The SI unit for acceleration is meters per second per second (m/s 2). Acceleration is one of the most basic concepts in modern physics, underpinning essentially every physical theory related to the motion of objects. In algebraic notation, the formula can be expressed as:Īcceleration can be defined as the rate of change of velocity with respect to time. Where v stands for velocity and t stands for time. acceleration = ( v Final− v Initial)/( t Final− t Initial).The general formula for average acceleration can be expressed as: “A motion is said to be uniformly accelerated when, starting from rest, it acquires, during equal time-intervals, equal amounts of speed.” - Galileo Galilei, Two New Sciences, 1638 After all, acceleration is one of the building blocks of physics. This cannot be added, subtracted, multiplied, or divided with other numbers and therefore returns an error.The acceleration formula is one of the basic equations in physics, something you’ll want to make sure you study and practice. The second reason is an input that contains non-number characters such as a letter. This situation will return infinity and throw an error. The first is an input that results in dividing by zero during calculations. There are two main reasons for invalid inputs causing an error. If the solution is not a finite number, it will throw an error and ask the user to check their inputs. The code also contains logic for catching errors. The function also takes care of all unit conversions for the inputs and output. It takes the inputted numbers, applies them to the applicable formula, then rounds the answer to the fifth decimal place. This function utilizes all of the equations that were listed in the lesson above. When you click the “calculate” button, the acceleration function runs. ![]() This allows a near-instant calculation of the solution. Internet browsers have a built-in JavaScript engine that can run this calculator inside the browser. The calculator on this page is written in the programming language JavaScript. If we are given time instead of distance, we would use equation 1. For example, if we are given the values for initial velocity (v 0), final velocity (v), and distance (Δx), we would use equation 2. We choose a kinematic equation based on what parameters we already know. After rearranging the terms in these three equations to solve for acceleration, they are given as: ![]() There are four kinematic equations, but only three of them can be used to solve for acceleration. These equations are known as the kinematic equations. Of course, we do not always know the change in velocity and elapsed time, so we must sometimes use other equations to solve for acceleration. Where a is the acceleration of the object, Δv is the change in velocity, and t is the amount of time the change in velocity takes. In its simplest form, the equation for acceleration is given as: Acceleration is defined as the rate of change of velocity for an object.
