Acceleration can be defined as the rate at which the velocity of anything changes with respect to time. If we take any object into consideration we can also define acceleration as the net sum of all the forces which are acting on the body now this is in accordance with Newton’s second law.

Now as we have defined Acceleration as the rate of change of velocity then we can say that if velocity increases then we can say that there is a change in the velocity and in addition to this if the velocity decreases then also it is the change in velocity hence we conclude that

## Acceleration calculator

if the velocity changes in increasing order then it is accelerating and if the velocity decreases then it is a special type of acceleration which is called retardation, hence when we apply the brake in any moving vehicle the vehicle retards and if we apply acceleration then the vehicles speed increases and we say that the vehicle is accelerating.

now acceleration is an vector Quantity that means if the angle or direction changes then, there is a change in velocity and hence the body is accelerating, now in order to understand this we can take an example of a body which is moving with a uniform speed but in an circular motion, here at every point the direction of propagation changes therefore we can say that there is a change is velocity and the body is accelerating.

**HOW TO CALCULATE ACCELERATION **

as we have said that acceleration is the rate of change of velocity, hence the simplest way to calculate acceleration we be DV/DT, this means that rate of change of velocity this we can get with differentiation of velocity with respect to time.

another way to calculate acceleration is using the equation **F=ma**, according to this equation, if any force F is applied to a body which is of mass M then the body will be accelerated with a change in velocity equal to a.

in addition to this, we can use the fundamental equation of mechanics which is **2as=v*v-u*u**, in this equation putting v as final velocity, u as initial velocity and s as total distance covered one can calculate the an as acceleration

**Units **

- The SI unit of acceleration is Metre per Second Square which is M/sec*sec here one thing to note here is that 1 unit acceleration is when there is unit change is the velocity.

**TYPES OF ACCELERATION **

- Average acceleration is considered when we have average change is velocity and the average change in time.
- Instantaneous acceleration, it is the acceleration when we considered a change in velocity at any instance, now in order to calculate instantaneous acceleration you have to find the first-order derivative of the change in velocity with respect to time.
- Uniform acceleration, when the rate of change of velocity is constant.
- Non- uniform acceleration, when the rate of change of velocity is not constant.
